This study is first to elucidate the efficacy of electrochemical activation of periodate (PI) by permanganate (PM) in enhancing the degradation of bisphenol A (BPA) over a wide pH spectrum. Utilizing a current density of 4 mA/cm 2 , 200 μM PI, and 20 μM PM, the proposed system achieved a 99.8 % degradation of 40 μM BPA within 30 min and a 65.5 % total organic carbon (TOC) removal in 120 min. The combined system yielded a synergistic coefficient of 15.23 for BPA degradation, and energy efficiency of 0.14 KWh•m −3 . The exceptional performance is attributed to the reduction of PM to low-valent manganese species at the cathode, which facilitates the activation of PI. Additionally, the system preserved high BPA degradation efficiency across a pH range of 3–11. Radical quenching and electron paramagnetic resonance spectroscopy experiments confirmed the pivotal role of singlet oxygen in the degradation process. Furthermore, the system exhibited relative insensitivity to actual water matrix constituents, including inorganic ions and humic acid. In conclusion, the proposed system constitutes an eco-friendly treatment process for BPA removal characterized by low energy consumption.

Bisphenol A (BPA) is an environmental endocrine-disrupting compound that is resistant to conventional biological treatment, making it crucial to develop an oxidation process. This study introduces a novel hydrodynamic cavitation (HC) coupled with a Fenton + periodate (PI) oxidation system for the efficient degradation of BPA. By systematically examining the key parameters such as inlet pressure, Fe (II),H2O2, and PI concentration, it was found that HC performed optimally at a pressure of 0.5 MPa. A conversion of 98.14% was achieved within 60 min when the molar ratio of BPA, Fe (II),H2O2, and PI was approximately 1:1:5:1. Further analysis revealed that the gray correlation betweenH2O2and PI concentrations on the degradation efficiency was 0.833 and 0.843, respectively, indicating that both of them had significant effects on the degradation process. The free radical quenching assay confirmed the hydroxyl radical (•OH) as the main active substance. Additionally, the toxicity of the degradation intermediates was evaluated using the Toxicity Estimation Software Tool (TEST). An artificial neural network (ANN)-based model was constructed to predict the BPA-degradation process, facilitating precise reagent dosing and providing robust support for the intelligent application of water-treatment technologies.

Chitin , a kind of polysaccharide mainly obtained from food waste, has emerged as an important biodegradable biopolymer in composite materials. The difficulty of aldehyde modification, which greatly limited the application of chitin nanocrystals , was addressed by applying a facile route of partial deacetylation followed by periodate oxidation in this study. Deacetylation occurred on the surface of both crystalline and amorphous regions, which were significantly degraded in the following periodate oxidation due to the inevitable cleavage of chitin chains, leading to an increase in the crystallinity index of obtained di-aldehyde chitin. The degree of deacetylation and periodate addition had limited improvement in the aldehyde content of di-aldehyde chitin with a maximum value of around 0.42 mmol/g. With further 2,2,6,6-tetramethylpiperidine-1-oxyl-mediated oxidation, the carboxyl content of tri-carboxyl chitin was improved to 1.58 mmol/g, which played a critical role in the dispersion efficiency and morphology of chitin nanocrystals. The obtained rod-like chitin nanocrystals with a ζ-potential value of −42 mV and an average size of 97 nm have potential application in dye-adsorption and emulsion stabilizers.

Oxidized xanthan gum with different aldehyde content is successfully prepared by periodate oxidization and used as a crosslinking agent for gelatin edible films . X-ray diffraction measurements and atomic force microscopy images demonstrate that degradation is concomitant with the oxidization process, leading to the decrease in crystallinity and the structure changes. Glycerol-plasticized gelatin–xanthan gum and gelatin–oxidized xanthan gum edible films are prepared using casting techniques. The optical properties studies show that all films are very transparent and have excellent barrier properties against UV light. Introducing aldehyde groups can improve the UV barrier properties, resulting from the increased C N groups by Schiff's base formation. Properties studies show that xanthan gum can drastically reduce the total soluble matter, moisture content and water vapor permeability and greatly improve the mechanical properties and thermal stability of gelatin films. With the increase of oxidization level of oxidized xanthan gum, the enhancement of water barrier properties, mechanical properties and thermal stability of gelatin–oxidized xanthan gum films is observed, which is mainly due to the covalently linking between the two polymers. Subsequently, the excessive degradation of xanthan gum will reduce the mechanical properties and thermal stability of gelatin films.

To investigate the relationship between the degree of surface oxidation of delignification materials and their dielectric properties, sodium periodate was used to oxidize the delignification samples of Pinus sylvestris var. Mongolia and Paulownia fortunei (Seem.) Hemsl. The degree of oxidation was reflected by the degree of substitution of aldehyde and carboxyl groups at a specific reaction time interval, and then the dielectric constant and dielectric loss tangent were measured. The results show that with the increase of oxidation time, the crystallinity decreases and the hydrogen bond network is weakened. In the frequency range of 103–107 Hz, the dielectric constant of the sample decreases with the increase of frequency and tends to be stable near 10 MHz, but the dielectric constant of the oxide material is significantly higher than that of the untreated material. At the same time, the dielectric constant increases with the increase of oxidation time, while the dielectric loss tangent decreases.

The exploitation and utilization of natural fibers still face many challenges due to their high crystallinity and extensive hydrogen bond network. Therefore, sustainable and effective modification strategies are currently essential. In this work, we investigate the processing and mechanical performances of natural fibers modified by combining sodium periodate oxidation and subsequent Schiff base reaction. Steam-exploded hemp fibers (HFs) were firstly oxidized with sodium periodate, and subsequently grafted with 1,10-diaminodecane. A decrease in the glass transition temperature of oxidized-aminated HFs (OAHFs) from 225 to 150°C was achieved as the dosage of periodate increased. Admirable mechanical properties were achieved despite a lower dosage of periodate due to melt bonding and chemical cross-linking between the fibers during heat processing. Particularly, dynamic compression molding was applied to heat processes and effectively improved the melt bonding and the chemical crosslinking, which increased flexural strength from 58.2 to 69.9 MPa. This strategy was moderate and low cost. The resulted material has good processing performance and excellent mechanical properties, which have large industrial application prospects and potential in the field of biodegradable environment-friendly materials.

In this study, manganese oxide supported biochar (MBC) was used as a catalyst of periodate (PI) for the oxidative degradation of sulfonamide antibiotic sulfamethazine (SMZ). The degradation rate of 10 mg/L SMZ reached 99 % in 60 min in the MBC/PI system, and the optimal condition was pH 3.5, 0.12 g/L of MBC, and 0.17 mM of PI. Combined with quenching experiment and electron paramagnetic resonance (EPR) characterization, it was determined that the reactive oxygen species (ROS) participating in the reaction include iodate radical (IO 3 ∙), singlet oxygen ( 1 O 2 ), and hydroxyl radical (∙OH). ROS, Mn(III) and electron transfer are three crucial SMZ removal mechanisms in MBC activated PI system, and the conversion process of reactive species was deduced. The manganese redox cycles, oxygen-containing functional groups on MBC surface, and BC-O-Mn(II) complex participated in reactive species production. The loading of manganese oxide increases the number of oxygen-containing functional group on the surface of BC, and BC-O-Mn(II) complex formation resulted in the higher catalytic activity compared with BC. Ten SMZ oxidative products and four transformation pathways was identified. This study provided an efficient and practical method to remove sulfonamide antibiotics and revealed its theoretical mechanism.

Periodate-based advanced oxidation processes (PI-AOPs) activated by carbon catalysts have shown promising application prospects in the removal of emerging contaminants. Herein, a series of N-doped carbon catalysts (NC) were prepared by in-situ pyrolysis of N-containing polymers (polyaniline) to unveil the potential mechanism of N dopants on PI activation. The optimized sample NC700 showed a satisfying degradation performance, achieving 100 % removal of bisphenol A (BPA) at a concentration of 10 mg/L within 90 min in the presence of 0.1 mM PI. The impacts of various N types on PI activation were systematically investigated by dynamic fitting and density functional theory computations. These analyses highlighted the crucial role of graphitic N configuration on carbon surface, which exhibited the highest adsorption energy and a positive correlation with the normalized degradation efficiency. The chemical quenching experiments and electrochemical experiments confirmed that the BPA oxidation mechanism was primarily mediated electron transfer by [NC-PI]* complex, with singlet oxygen ( 1 O 2 ) /superoxide radicals (O 2 •– ) playing a supplementary role. In situ ATR-SERAS measurement strengthened the understanding of PI activation by carbon catalyst based on electron transfer pathway. Owing to the non-radical oxidation mechanism, the NC/PI system had a broad pH adaptability and great anti-interference ability against typical wastewater components. This study provides mechanistic insights into the carbon-driven PI activation process for wastewater treatment, advancing the practical application of PI-AOPs.

Thermoplastic bio-based materials from lignocellulosic fibers are of great importance in a sustainable society. To enhance their preparation to an industrial scale, a facile strategy is proposed that combines continuous steam explosion (CSE) with periodate oxidation/borohydride reduction to modify sisal fibers . In the CSE pretreatment , the aldehyde content of oxidized products was increased by a maximum of ∼17%, and the yield of oxidized/reduced products was increased by a maximum of 25%. Furthermore, the tensile strength of hot-pressed sheets was increased to 42.2 MPa, representing a 175% improvement compared with sheets without CSE pretreatment, and a decreased glass transition temperature of ∼132 °C. Results indicated that CSE pretreatment was favorable for improving the modification efficiency and uniformity of sisal fibers, simultaneously achieving much better mechanical properties and thermoplasticity . Appropriate oxidation level of sisal fibers also achieved the better performances. The combined strategy was facile and scalable, and might significantly impact the widespread preparation and utilization of thermoplastic bio-based materials.

Dialdehyde nanocellulose (DANC), obtained via periodate oxidation, has been widely used in foods, cosmetics, and biomedical fields due to its unique characteristics. However, the high-crystallinity and tight structure of cellulose retards the efficiency of periodate oxidation for producing DANC. Herein, a novel sustainable and clean approach with less energy consumption and low cost was developed through LiBr·3H2O (LBTH) non-dissolving pretreatment, which can shorten the oxidation time of the followed periodate oxidation and reduce the oxidant consumption. It was shown that the cellulose Iβ structure of hardwood dissolving pulp (HDP) was largely transformed into an amorphous structure after LBTH non-dissolving pretreatment for 30 min, and the corresponding crystallinity of HDP was reduced from 83.2 to 48.7%. After pretreatment for 60 min, the aldehyde group content of the obtained DANC increased by around 30% compared to the control without pretreatment while the operational cost was reduced by 45%. Moreover, the fabricated DANC showed strong antibacterial activity against both Escherichia coli and Bacillus subtilis. LBTH was recovered and reused, and the pretreatment effectiveness was also maintained. This study provides a sustainable, cost-effective, and clean approach for the preparation of DANC and will promote the application of cellulose nanomaterials.

Periodate (PI) shows promising potential as an oxidant for wastewater treatment; however, its impact on the toxicity of wastewater remains unknown. Here, we found that with 100 μM PI addition, the cytotoxicity of wastewater increased from 4.8 to 7.6 mg-Phenol/L to 9.5 to 12.8 mg-Phenol/L, and genotoxicity increased from 0.3 to 0.9 μg-4-NQO/L. Interestingly, hypoiodous acid (HOI) was not detected during the reaction, and there was no observed increase in the concentration of total organic iodine (TOI). CHON components in dissolved organic matter changed most obviously in PI oxidation, which might serve as primary precursors for toxic byproducts. Cytotoxicity of typical nitrogen-containing precursors of tryptophan, lysine, phenylalanine, and tyrosine after PI oxidation increased from not detected to 14.7, 2.4, 4.1, and 3.2 mg-Phenol/L, respectively. Here, four nonhalogenated aromatic nitrogenous byproducts (N-DBPs) of 3-hydroxyquinoline, 4-hydroxyquinoline, benzopyridine, and benzopyrrole were confirmed using standards, and four byproducts such as 2-formylbenzonitrile were tentatively proposed. The cytotoxicity of the four confirmed byproducts was comparable to those known N-DBPs such as nitrosamines, suggesting attention should be given to these nonhalogenated but nitrogenous byproducts. The four confirmed byproducts were detected in two PI-treated wastewater samples with concentrations of 0.8, 0.98, 0.52, and 0.0038, and 18.28, 1.50, 0.57, and 0.0074 μg/L, respectively, with contributions less than 1.5% to the overall cytotoxicity. Further investigations are warranted to elucidate the primary drivers of toxicity in PI-treated wastewater.

Glycosylation on the cell surface contains abundant biological information, and detecting the glycan on cell surfaces can offer critical insight into biology and diseases. Here, a signal amplification strategy for the sensitive detection of glycan expression on the cell surface was proposed. In this approach, glycans on the cell surface were detected with poly(glycidyl methacrylate)-grafted silica nanosphere labeled with quantum dots (QDs) and biotin through the specific affinity reaction of avidin-biotin on the cancer cells. Glycans on the cell surface were first labeled via selective oxidization of sialyl groups into aldehydes by periodate . Aniline-catalyzed hydrazone ligation with biotin hydrazide was then used for the specific recognition to avidin . The nanoprobe was fabricated with “living” SiO 2 nanoparticles with alkyl bromide groups on their surfaces. They were then subsequently grafted with poly(glycidyl methacrylate) (PGMA) brushes via the successive surface-initiated atom transfer radical polymerization . The CdTe QDs and biotin were immobilized through a ring-open reaction with epoxy groups in the PGMA brushes to obtain QDs/biotin-polymer brush-functionalized silica nanosphere (SiO 2 -PGMA-QDs/biotin). Enhanced sensitivity could be achieved by an increase in CdTe QDs loading per assay event, because of the large number of surface functional epoxy groups offered by the PGMA. As a result, fluorescence signal increased versus the unamplified method. This method successfully demonstrates a simple, specific, and potent method to detect glycans on the cell surface.
