With the utilization of degradable plastics in the agricultural film and packaging industries, degradable microplastics (MPs) with strong mobility distributed in the underground environment may serve as carriers for heavy metals. It is essential to explore the interaction of (aged) degradable MPs with Cd(Ⅱ). The adsorption and co-transport behavior of different types of (aged) MPs (polylactic acid (PLA), polyvinyl chloride (PVC)) with Cd(Ⅱ) were investigated through batch adsorption experiments and column experiments under different conditions, respectively. The adsorption results showed that the adsorptive capacity of (aged) PLA with O-functional groups, polarity, and more negative charges was stronger than that of PVC and aged PVC, which was attributed to the binding of (aged) PLA to Cd(Ⅱ) through complexation and electrostatic attraction. The co-transport results indicated that the promotion of Cd(Ⅱ) transport by MPs followed the order of aged PLA > PLA > aged PVC > PVC. This facilitation was more pronounced under conditions of stronger transport of MPs and favorable attachment of Cd(Ⅱ) to MPs. Overall, the combination of strong adsorption affinity and high mobility helped (aged) PLA act as effective carriers for Cd(Ⅱ). The DLVO theory well explains the transport behavior of Cd(Ⅱ)-MPs. These findings provide new insights into the co-transport of degradable MPs and heavy metals in the subsurface environment.

Three new multi-dimensional coordination polymers, namely, [Cd(SIP)(HBPP)(BPP) 0.5 (H 2 O)·H 2 O] n ( 1 ), [Zn(L)(BIB) 0.5 ] n ( 2 ), and {[Cd 2 (L) 2 (BIB) 2 ](H 2 O) 7 } n ( 3 ) (H 3 SIP = 5-sulfo-1,3-benzenedicarboxylate, BPP = 1,3-bis(4-pyridyl)propane, H 2 L = 4-oxyacetate-benzoic acid, and BIB = 1,4-bis(imidazol-1-yl)-butane), were hydrothermally synthesized by self-assembly of the flexible N-donor ligand and the polycarboxylate ligands. Single crystal X-ray analyses reveal that complexes 1 – 3 possess different structural features. The Cd(II) atom in complex 1 is seven-coordinated by two bidentate chelating carboxylate groups and two nitrogen atoms as well as one water molecule. The adjacent Cd(II) atoms are bridged by two carboxylate groups to form 1D chains running along different directions, which are connected by BPP ligands to generate 2D network. The resulting 2D networks are further linked by hydrogen-bond interactions, affording a 3D supramolecular architecture. In complex 2 , the [Zn 2 (COO) 4 ] units are bridged by L 2− ligands to generate 1D double chain structure and then linked by BIB ligands to give 2D grid framework. In complex 3 , the [Cd(L 2 )] n and [Cd(BIB)] n helixes are alternately arranged, leading to the formation of a 2D bilayer structure.

In this paper, Cd(OH)2 1D three-side nanobelt architectures have been fabricated through a facile two-phase reaction system. Considering their electropositive character proven by zeta potential measurement, the as-obtained Cd(OH)2 nanomaterials have been applied to capture negatively charged DNA. On the basis of the above results, the Cd(OH)2 nanomaterials have been employed for trapping negatively charged double-stranded DNA molecules (salmon sperm DNA). Assisted by the detailed observation of their DNA interaction results as well as through UV–vis spectroscopy, infrared imaging automatic target recognition (IRATR) and inductive coupled plasma atomic emission spectrometer (ICP-AES) measurements, it has been clearly shown that this 1D nanoarchitecture can effectively trap and release DNA molecules without use of any other organic reagents. In addition, a miniaturized electrochemical DNA-releasing device based on the Cd(OH)2 1D three-side nanobelt architectures has been fabricated. Using this device, it is possible to recycle the Cd(OH)2 nanostructures. In addition, the Cd(OH)2 nanomaterials maintain their nanostructures, and no Cd2+ ions were released in repeated DNA separation and transfer processes, which demonstrate their practicality for DNA trapping.

In this study, a tumor-targeting and pH-sensitive inclusion complex based on the host–guest recognition between the chitosan and folic acid grafted HP-β-CD (FA–CS–CD) and stearic acid modified 2-benzimidazolemethanol (BM-SA) was designed and fabricated for the controlled delivery of paclitaxel (PTX). Through the combination of computational simulations and experiments, the interaction between FA–CS–CD, BM-SA, and PTX was investigated, and the optimized preparation method was obtained. For the optimized PTX-loaded FA–CS–CD/BM-SA inclusion complex, the particle size and zeta potential were 146 nm and +15.4 mV, respectively. In vitro drug release study revealed the pH-triggered drug release behavior of the inclusion complex. Both in vitro and in vivo evaluations demonstrated that the PTX-loaded FA–CS–CD/BM-SA inclusion complex exhibited enhanced antitumor efficiency and minimized systemic toxicity. This system might be a promising carrier for PTX.

Many Industrial effluents contain high concentrations of Cd(II) and Pb(II), which are serious problems for causing threat to human health. Adsorption has drawn considerable attention owing to its high efficiency and easy operation. In this paper, nanoscale nitrogen-doped aerogel microspheres (NCA) was synthesised through polymerization of phenolic resin and melamine in an emulsion suspension system. Factors influencing the adsorption properties of NCA and carbon aerogels microspheres (CA) toward Cd(II) and Pb(II) ions were studied, namely, pH, adsorbent content, initial Cd(II) and Pb(II) concentrations, and contact time. Furthermore, three models isotherm including Langmuir, Freundlich, and Sipss and three kinetic models were used in interpreting the adsorption process. NCA exhibited an excellent adsorption property and maximum removal capacity of 935.56 mg·g −1 for Pb(II) and 282.07 mg·g −1 for Cd(II). Results from XPS analysis implied that the amount of Pb absorbed by NCA was higher than that of CA mainly because of the complexing effect of nitrogen-containing functional groups on Pb(II). Furthermore, density functional theory (DFT) calculations confirm that N doping is beneficial to Pb(II) adsorption. These results suggested that NCA can be used as an adsorbent for the removal of Cd(II) and Pb(II) from industrial effluents.

In this work, CuS@Cu-CD composites were synthesized and employed as Fenton-like catalysts. CuS significantly enhanced the photodegradation activity of tetracycline (TC) when decorated with Cu-doped-carbon dots (Cu-CDs). The influence of initial pH, dosage of catalyst, and H2O2 concentration on the catalyst performance was investigated. Radical trapping experiments proved that ·O2− and h+ played critical roles and ·OH played a moderate role in the degradation of TC. Mechanism analyses demonstrated that Cu2+/Cu+ redox circulation could be accelerated by the introduction of Cu into carbon dots, which further facilitated H2O2 consumption and resulted in higher TC degradation efficiency.

Fe3O4/MOF (metal organic framework)/L-cysteine was synthesized and applied for the removal of Cd(II) from wastewater. The adsorption kinetics and isotherms were investigated, and the results indicated that the adsorption obeyed the pseudo-second-order kinetic model and Langmuir isotherm. The maximum adsorption capacity was calculated to be 248.24 mg g−1. Fe3O4/MOF/L-cysteine was further applied to determine trace amounts of Cd(II) in real water samples using ICP-AES (inductively coupled plasma-atomic emission spectroscopy) based on magnetic solid-phase extraction (MSPE). The determination limit was 10.6 ng mL−1. Additionally, Fe3O4/MOF/L-cysteine can also be used as a fluorescent sensor for “turn-off” detection of Cd(II), and the detection limit was 0.94 ng mL−1.

Recycling of kerf-loss slurry waste has become a meaningful and urgent issue in recent years. In this study, a novel hybrid material was prepared by Ag-assisted chemical etching kerf loss silicon waste and subsequently functionalized by a facile three-step graft process of 3-aminopropyltrimethoxy-silane, maleic anhydride, and ethylenediamine, named as EDA-MAH-APTES-NPSi, which could work as an effective adsorbent for removal of Cd(Ⅱ) from aqueous solution. The effect of initial pH, absorption duration, and metal ion concentrations on absorption performance were investigated. The adsorption equilibrium achieved after 120 min, the maximum adsorption capacity reached up to 210.01 mg/g and pH was at 5.5. The adsorption kinetic was fitted in the pseudo-second-order model and the Freundlich equation provided an accurate description for adsorption behavior. The XPS and FT-IR analysis manifested that Cd(Ⅱ) removal might be ascribed to the adsorption on the surface organic functional group by chemical chelating reaction and the ion exchange reaction. The EDA-MAH-APTES-NPSi maintained excellent adsorption capacity which decreased approximately 15.3 % (from 40.5–34.3 mg/g) after five successive regenerated cycles. The work confirms the potential of Cd(Ⅱ) removal from aqueous solution based on the modified NPSi and opens up a new way for recycling silicon cutting waste.

A novel thiosemicarbazide modified adsorbent (PAN MW –TSC) based on polyacrylonitrile fiber was successfully synthesized under microwave irradiation, which was applied for the uptake of Cd(II) and Pb(II) from aqueous solution subsequently. Microwave irradiation method is a new approach to achieve the modification and it turns out that just a 30 min process is enough for the anchoring of functional groups in the fiber matrix. The surface characterization was performed by fourier transform infrared spectroscopy (FT–IR), scanning electron microscopy (SEM) elemental analysis (EA) and thermogravimetric analysis (TGA), indicating that the modification was successfully accomplished. Batch adsorption experiments including equilibrium isotherms, kinetics and the effects of pH and temperature on the adsorption of Cd(II) and Pb(II) were systematically studied. Among three kinetic models, the pseudo-second-order kinetic model provides the best correlation for the process. The nonlinear resolution of the Langmuir isotherm equation has been found to show the closest fit to the equilibrium date. Thermodynamic parameters, involving △ G , △ H and △ S were also calculated from graphical interpretation of the experimental data, which suggest that metal ions adsorption onto PAN MW –TSC fibers is spontaneous and exothermic. Regeneration of PAN MW –TSC fibers loaded with metal ions was efficiently done with 0.5 M HNO 3 , by which the investigated adsorbent could be used reproductively for five times with a small decrease in sorption capacity. The feasible preparation of PAN MW –TSC fibers with high adsorption capacities opens a new perspective in the potential application for wastewater treatment .

Large scale of Cd-contaminated soil has become a serious threat to environmental safety and human health, whereas field applicability of existing remediation technologies has encountered numerous obstacles, such as poor stability, secondary pollution, long operation time, and high chemical cost. Herein, a novel activated calcite with significantly enhanced immobilization stability of Cd in soil has been synthesized based on mechanochemical technology. Our results demonstrate that the passivation rate of bioavailable Cd in Cd-contaminated soil (initial concentration 3 mg/kg) could be maintained at 65 % after 50 days of passivation cultured with activated calcite. Mechanistic studies have revealed that the outstanding performance is attributed to the enhancement of the CO 3 2– and Ca 2+ release properties of calcite through mechanical activation, leading to a 550 % increase in Ca 2+ release. The CO 3 2– fraction binds in situ to the free Cd in the soil, forming a stable carbonate-bound state. Simultaneously, the OH – released from the continuous hydrolysis of CO 3 2– effectively regulates and stabilizes the soil pH within the neutral range. Further, SEM-EDS and sequential extraction procedures (SEP) analyses implied that the specific adsorption of Cd by in-situ formed iron oxides in soil was visibly related to the release of OH – from activated calcite and immobilized the free state Cd in the more stable iron oxide-bound state. The current work shows the high sustainability and stability of Cd-contaminated soil immobilization by activated calcite materials.
