CuSO 4 is frequently employed as a control measure for the emergency treatment of cyanobacterial harmful algal blooms. Concurrently, nano-plastics (NPs) have emerged as pervasive pollutants exacerbating the threat of eutrophication to aquatic ecosystem. However, there is little known regarding the influence of NPs on the efficacy of copper sulfate (CuSO 4 ) in controlling cyanobacterial harmful algal blooms (cyanoHABs). Here, we demonstrate that the co-existence of polystyrene nanoplastics (PS NPs) exacerbates the negative effects of CuSO 4 to photosynthetic activity of Microcystis aeruginosa . This is caused via the differences in disrupting light energy absorption, inactivation of the reaction center, as well as disruptions in electron transport and metabolic pathways, which collectively induce oxidative stress and damage cell membrane. Treatment with either NPs or CuSO 4 alone results in the downregulation of carbon-fixation, the tricarboxylic acid cycle, and pyruvate metabolism. Co-existence of NPs significantly influenced ABC transporters, carbon fixation, and the two-component system in M . aeruginosa . Notably, while single CuSO₄ treatment increased microcystin- leucine arginine (MC-LR) levels by 243.3 % relative to controls, combining CuSO₄ with NPs (PS, PS-NH₂, PS-COOH) significantly reduced MC-LR concentrations by 73.5 %, 90.2 %, and 70.7 %, respectively (p < 0.05). This study demonstrated that NPs exacerbated the oxidative stress induced by CuSO 4 on M . aeruginosa cell, while concurrently reducing MCs release. Furthermore, the underlying molecular mechanisms were systematically investigated. These findings provided novel insights into the crucial importance of considering NPs impact prior to the application of CuSO 4 for the management of (cyanoHABs).

A polymerizable complex of copper(II) ion with unsaturated quaternary ammonium cation-modified salicylaldoxime ligand was prepared and used to synthesize a novel copper(II) ion imprinted polymers (Cu(II)-IIPs). Elemental analysis (EA), Fourier transform infrared spectroscopy (FTIR), and NMR spectroscopy confirmed the structures of the polymerizable complex and Cu(II)-IIPs. Thermogravimetric analysis (TGA), Brunauer–Emmett–Teller surface area analysis (BET), and scanning electron microscopy (SEM) characterized physical properties and morphologies of synthesized metal complex and corresponding polymers. The effect of pH, contact time, and initial Cu 2 + and SO 4 2 − concentration on the simultaneous adsorption of Cu 2 + and SO 4 2 − ions of Cu(II)-IIPs were investigated. Cu(II)-IIPs showed high hydrophilicity and simultaneously rapid adsorption of Cu 2 + and SO 4 2 − from solution. Moreover, Cu(II)-IIPs displayed highest adsorption capacity in the pH range of 5.0–6.5, the separation factor ( β ) between Cu 2 + with respect to Fe 3 + was 1866, the equilibrium adsorption capacities for Cu 2 + and SO 4 2 − were almost the same and close to 0.13 mmol g − 1 at 25 °C. Stripping experiments revealed that 1.5 mol L − 1 H 2 SO 4 was an effective eluent for desorbing copper (II) ions from Cu(II)-IIPs. In additional, Cu(II)-IIPs exhibited good recyclability and reusability for 5 cycles without deterioration of its selective ion-absorbing capacity.

In order to visually display the migration and crystallization process of salt solution in porous cultural relics, copper sulfate solution with color rendering property was selected to record the migration, crystallization and resolution of salt solution in simulated SiO2samples under different environmental conditions in real time through high-resolution recording system, scanning electron microscope system, salt phase X-ray diffraction system, and so on. The results showed the migration of salt solution in porous samples was related to the structural characteristics of the porous samples, the migration rate of salt solution, the evaporation rate and the change frequency of crystallization–resolution, etc., in which the large pore size of the sample, the higher the concentration and the faster migration and evaporation rate of salt solution, the greater the change rate of the brine accumulation zone or salt crystallization zone in the different porous samples. During the humidification–drying cycles of rainfall, the higher the cycle frequency of humidification–drying was, the higher the drying temperature was, the more frequent the crystallization-analysis change of salt in the salt-bearing sample was, and the more extensive the distribution of salt crystal zone was. This is the first time to visualize the salt belt by simulating the changing process of a salt solution with a color rendering property in porous samples. This has scientific theoretical guidance for the study of the migration–crystallization changes of soluble salts contained in porous silicate cultural relics. The visibility analysis results of multilayer salt crystal belts can also provide the preliminary basis for further effective desalination of salt bearing cultural relics.Keywords:color rendering tracing;copper sulfate;porous cultural relics;crystalline brine accumulation zone;salt crystalline zone

The increasing presence of pharmaceutical contaminants, such as dipyrone (DIP), in water systems highlights the urgent need for innovative and sustainable remediation technologies. This study examined the degradation of DIP using a chalcopyrite (CP)-activated peracetic acid (PAA) system, highlighting its potential for the removal of pharmaceutical pollutants. Experimental and statistical parameter optimization suggested that approximately 85.5 % of DIP degradation and 60 % of mineralization were achieved with CP (4 g/L) and PAA (10 mM) at neutral pH. Scavenger and probe experiments confirmed the presence of hydroxyl radicals ( • OH) and alkyl radical species in the CP/PAA system, but •OH was the primary contributor to DIP degradation. The surface-active sites confirmed that heterogeneous Cu(I) exerted more significant influence than Fe (II) of CP, producing 4.21 and 2.35 mg/L, respectively. The presence of reductive sulfur species in the CP allowed the capture of additional protons, creating sulfur vacancies and further strengthening the cycling of Cu and Fe species. DFT analysis confirmed that the FeCuS 2 -Fe adsorption energy (−3.71 eV) and the HOMO-LUMO gap of FeCuS 2 -Fe (0.03 eV) were critical to produce radicals. The CP/PAA system is suitable for DIP degradation and contributes significantly to the degradation of other environmental pollutants. It retained its capacity to degrade above 65 % for up to five consecutive cycles, offering a new and innovative method for water treatment.

Catalytic wet air oxidation (CWAO) is a promising sludge treatment technology, and Cu ions were commonly used as homogeneous catalysts. However, the transformation of Cu ions in CWAO has not been investigated. This study conducted CWAO experiments using CuSO 4 as the catalyst to reveal the change in Cu forms and catalytic performance. The results showed that Cu ions increased the mineralization rate of organic matter by at least 12 % and notably enhanced the degradation of humic acids. During the reactions, Cu ions were first complexed with organic substances and finally became stable CuS/Cu 2 S slag with a ratio close to 90 %. However, all the forms of Cu exhibited similar catalytic effects. To check the result further, chalcopyrite, which has an identical mineral composition to the CuS/Cu 2 S slag, was used in CWAO to replace CuSO 4 . The result verified that chalcopyrite had the same catalytic ability, and at most 88 % of organic matter was mineralized. Therefore, this study revealed the essential characteristics of homogeneous CWAO and found an effective and cheap catalyst without a heavy burden of copper recovery from the effluent. The finding provides a more cost-effective solution for sludge treatment.

Copper nanoparticles (Cu-NPs) were widely used in various industrial and commercial applications. In this study the effects of Cu-NPs and soluble Cu were investigated on juvenile Epinephelus coioides . The fish were exposed in triplicate to control, 20 or 100 μg Cu L −1 as either copper sulphate (CuSO 4 ) or Cu-NPs in a semi-static aqueous culture for 25 days. The growth parameters were significantly lower at 100 μg Cu L −1 as CuSO 4 or Cu-NPs treatment compared to control. Time-dependent Cu accumulation in all tissues increased with increasing the Cu dose. The percentage of total Cu found in remaining tissues (head, bones, fins, etc.) decreased more in the CuSO 4 than Cu-NPs treatment after 25 days, but increased in all other tissues (especially in liver). Compared with the control, either Cu-NPs or CuSO 4 induced higher malonaldehyde concentration in tissues by overwhelming total superoxide dismutase activity, total glutathione concentration and Na + /K + -ATPase activity, but the opposite results were recorded for the brain. With increasing the CuSO 4 or Cu-NPs dose, apoptosis was exacerbated in the liver and gills, more so by CuSO 4 than Cu-NPs. Overall, these findings showed that Cu-NPs had the toxic effects similar to dissolved Cu; hence, Cu-NPs need to be included in the assessment of toxicological impacts in the aquatic environment.

Simple SummaryCopper sulfate and copper glycinate have been used as additives for copper supplementation and growth promotion in the swine feed industry. However, their effects on the gut microenvironment, especially for the fecal microbiota and metabolites, still remain unclear, which are the important indicators of gut health. As well as the nutrient digestibility and physiological and biochemical indices of pigs, the effects of copper sulfate and copper glycinate on fecal microbial communities and metabolic profiles were investigated to understand it better in the present study. Our results suggested that copper sulfate and copper glycinate could differentially affect fecal microbiota and metabolites, by which dietary copper glycinate exerted more beneficial effects on the gut health of pigs.AbstractThis study aims to compare the fecal microbiome-metabolome response to copper sulfate (CuSO4) and copper glycinate (Cu-Gly) in pigs. Twelve Meishan gilts were allocated into the CuSO4group and the Cu-Gly group (fed on a basal diet supplemented with 60 mg/kg copper from CuSO4or Cu-Gly) paired in litter and body weight. After a two-week feeding trial, the Cu-Gly group had a higher copper digestibility, blood hemoglobin, and platelet volume and higher levels of plasma iron and insulin-like growth factor-1 than the CuSO4group. The Cu-Gly treatment increased the abundance of theLachnospiraceaefamily and the generaLachnospiraceae XPB1014,Corprococcus_3,Anaerorhabdus_furcosa_group,Lachnospiraceae_FCS020_group, andLachnospiraceae_NK4B4_groupand decreased the abundance of theSynergistetesphylum andPeptostreptococcaceaefamily compared to the CuSO4treatment. Moreover, the Cu-Gly group had a lower concentration of 20-Oxo-leukotriene E4 and higher concentrations of butyric acid, pentanoic acid, isopentanoic acid, coumarin, and Nb-p-Coumaroyl-tryptamine than the CuSO4group. The abundance ofSynergisteteswas positively correlated with the fecal copper content and negatively correlated with the fecal butyric acid content. The abundance of theLachnospiraceae_XPB1014_groupgenus was positively correlated with the plasma iron level and fecal contents of coumarin and butyric acid. In conclusion, Cu-Gly and CuSO4could differentially affect fecal microbiota and metabolites, which partially contributes to the intestinal health of pigs in different manners.Keywords:copper sulfate;copper glycinate;microbiome;metabolome;pigs;copper source

The interaction between macromolecules and metal ions plays an important role in biological macromolecules, Metallo-supramolecular polymers, and polymer/salt composite systems . However, the detailed information about the coordination bonds in polymer/inorganic salt complexes at solvent-free state was poorly understood. Particularly, studies of the differentiation between coordinate covalent bonding and ion-dipole interactions are lacking. Herein, we prepared a series of PVA-CuSO 4 composite films with varying CuSO 4 content via solvent casting to probe the effects of CuSO 4 content on the properties of the PVA-CuSO 4 composite films in terms of initial thermal degradation temperature (T d,i ), refractive index (RI), crystallinity as well as glass transition temperature (T g ). Surprisingly, the T d,i , and RI were not always increasing with the increase of CuSO 4 content. Instead, a maximum point happened for both T d, i , and RI at a CuSO 4 /PVA weight ratio of 1%. Furthermore, the lowest level of crystallinity and a turning point in the T g ∼ CuSO 4 content curve were observed when the CuSO 4 /PVA weight ratio was 1%. These results consistently indicated that the composite with a CuSO 4 /PVA weight ratio of 1% formed the largest amount of coordinate bonds, while the further increase of CuSO 4 content might lead to ion-dipole interactions, which could destroy the formation of coordinate bonds. Moreover, both XPS and UV–visible absorption spectrum showed that copper (II) ions were at different bonding states when CuSO 4 /PVA weight ratio was below and above 1%, proving the proposition that coordinate bonds in PVA-Cu 2+ composite saturated at a CuSO 4 /PVA weight ratio of 1%. Taken together, our results provided evidences for using a novel perspective to understand the coordination bonds formed in polymer/inorganic salt complexes at solvent-free state. Such findings could not only help to enrich the fundamental research but can also guide the future development of advanced polymer/salt complexes.

Copper (Cu) is an essential trace element in the production of swine. This study was conducted to investigate the effect of 3 different sources of Cu on growth performance, Cu metabolism, and intestinal microorganisms of finishing pigs, so as to estimate the bioavailability of the 3 sources for pigs. A total of 42 male finishing pigs (88.74 ± 5.74 kg) were randomly allocated to 7 treatments. The factors were 3 sources (CuSO 4 , Cu-glycine, Cu-proteinate) and 2 levels (5 and 20 mg/kg) of Cu, plus one negative control treatment (0 mg/kg added Cu level) for the entire 28-d experiment. The average daily gain (ADG) and feed to gain ratio (F:G) both increased when Cu was added. The Cu level in liver, bile, kidney, serum, lung, urine and feces rose ( P < 0.001) with increasing dietary Cu level regardless of the source. Meanwhile, pigs receiving organic Cu (glycinate or proteinate) retained more Cu and excreted less Cu than those receiving inorganic Cu (CuSO 4 ), which showed that organic forms were more bioavailable. At the transcriptional level, changes in the level and source of dietary Cu resulted in modulation of transporters. In the jejunal mucosa, import transporter high affinity copper uptake protein 1 ( CTR1 ) and export transporter ATPase copper transporting alpha ( ATP7A ) in supplemental Cu treatments were down-regulated compared to the control. Also, peptide transporter 1 ( PepT1 ) and lanine-serine-cysteine transporter, type-2 ( ASCT2 ) were significantly ( P < 0.01) up-regulated in 20 mg/kg Cu-proteinate and Cu-glycinate treatments, respectively. Microbial diversity was lowest in the 20 mg/kg CuSO 4 treatment, and the ratio of Firmicutes to Bacteroidetes was higher in added Cu treatments, especially Cu-glycinate treatment. These results indicate that uptake of different Cu forms is facilitated by different transporters and transport mechanisms, and compared with inorganic Cu, organic Cu provides benefits to intestinal microflora and reduces Cu excretion.

Copper sulfate (CuSO 4 ) is a ubiquitous component in natural minerals and industrial dusts. However, CuSO 4 has been believed usually that it has adverse effect on elemental mercury (Hg 0 ) removal from flue gas. Here, we offered a new insight into the effect of crystal water in copper sulfate on Hg 0 catalytic oxidation. The structure evolution of copper sulfate by density functional theory (DFT) calculation revealed anhydrous CuSO 4 crystal contributing to a better HCl adsorption which provided a precondition for Hg 0 oxidation. Experimental results about the catalytic activity sequence of CuSO 4 > CuSO 4 ·H 2 O > CuSO 4 ·5H 2 O with HCl confirmed the negative effect of crystal water on Hg 0 catalytic oxidation. To realize industrial application, supported catalysts CuSO 4 /α-Al 2 O 3 synthesized by wet impregnation method was employed for elemental mercury (Hg 0 ) oxidation and the results exhibited excellent performance in Hg 0 oxidation under 250 °C–400 °C. The Hg 0 conversion efficiency was above 97% in the presence of 2 ppm HCl + 6% O 2 at 300 °C. Combining computational and X-ray photoelectron spectroscopy (XPS) analyses together, Cu atoms exposure on the surface of anhydrous CuSO 4 were the critical active sites for Hg 0 oxidation and the reaction obeyed the Eley–Rideal mechanism.

The technology of simultaneous ammonia selective catalytic reduction (NH 3 -SCR) denitration and carbon monoxide (CO) oxidation is a proposed approach for synergistic purification of nitrogen oxides (NO x ) and CO from flue gas. However, the lack of highly efficient catalysts has hindered the widespread adoption and application of this technology. Herein, a series of CuSO 4 /TiO 2 (denoted CuS/Ti-X, X means calcination temperature at 400, 500, and 600 °C) catalysts was prepared to investigate their performance for simultaneous NH 3 -SCR denitration and CO oxidation. The results show that dispersing CuSO 4 on TiO 2 carrier induces the formation of surface Cu-O defect structure and reduces the stability of the Cu-O-S structure, which gives CuS/Ti-X catalysts a good redox property. Hence, the CuS/Ti-500 catalyst exhibits good catalytic activity in simultaneous removal of NO and CO, even in the presence of SO 2 . Reaction process investigation demonstrated that the presence of NO and NH 3 inhibits the adsorption of CO and consumes active oxygen species, thereby suppressing the CO oxidation reaction. In contrast, CO can promote the activation of NH 3 via activating the redox sites, which is conducive to the NH 3 -SCR reaction via the E-R mechanism. This study provides new insights into the strategic design of dual-functional sulfur-resistant catalysts for flue gas purification.

Due to the high toxicity of cyanide, researchers are trying to find an environmentally friendly and sustainable leaching process for precious metals. Thiosulfate is considered one of the most promising alternative leaching systems. Nevertheless, a traditional thiosulfate leaching solution generally consists of copper sulfate and ammonia, in which copper sulfate acts as oxidant and ammonia acts as copper ion stabilizer. However, ammonia is another toxic reagent. For this reason, a novel and eco-friendly system of copper sulfate-tartrate-thiosulfate was investigated for silver sulfide leaching in this work. The effects of rotation speed, temperature, initial pH, copper sulfate, tartrate and thiosulfate concentrations and different atmospheres on the dissolution rate of Ag 2 S were examined. The process of silver sulfide dissolution is controlled by chemical reactions with an apparent activation energy of 43.49 kJ/mol. The reaction orders of silver sulfide leaching with respect to copper sulfate, tartrate, and thiosulfate concentrations in copper sulfate-tartrate-thiosulfate solutions are 0.491, 1.366, and 0.916, respectively. A detailed dissolution route of Ag 2 S was proposed based on XRD analysis of intermediate products such as Ag 3 CuS 2 , AgCuS and (Ag, Cu) 2 S. XPS analysis indicated that elemental sulfur was determined to be the final oxidant product of sulfur ions from Ag 2 S.
