Summary: This study developed a sample called FA-ZVIbm by ball-milling zero-valent iron (ZVI) with formic acid (FA), which showed remarkable performance in removing heavy metal complexes, specifically Cu(II)-ethylenediaminetetraacetic acid (Cu(II)-EDTA). The addition of FA greatly enhanced the removal efficiency, increasing the removal rate constant by 80 times. The improvement was attributed to the formation of a ferrous formate (Fe (HCOO)2) shell on the surface of FA-ZVIbm, which facilitated the activation of reactive oxygen species (ROS) and the leaching of Fe3+.

Summary: This study used spherical chain-shaped nanophase zero-valent-iron (nZVI) with different metal loadings to simulate wastewater, forming bimetallic nanocatalysts (BNC). The Cu removal efficiency was highest in nZVI@Cu-800. The size of nZVI was found to increase by 181% at 55 degrees C compared to 25 degrees C. XANES/EXAFS spectra analysis revealed the presence of Cu2O in nZVI@Cu, indicating a reductive degradation mechanism. Overall, this study demonstrates that nZVI and BNCs can effectively convert harmful 4-NP into useful and high-value 4-AP.

Summary: The study found that zero valent iron can degrade nitrobenzene through both reduction and advanced oxidation under oxygen-limited conditions. The contribution of center dot OH to the degradation of nitrobenzene increases with time, with reduction remaining the main pathway of transformation. The balance between ZVI, dissolved oxygen, and iron-complexing ligands is crucial for the optimal removal of organic contaminants.

Summary: This paper discusses the efficiency and mechanism of using nitrilotriacetic acid (NTA) as a complexing agent to enhance the zero-valent iron (Fe0)/peroxymonosulfate (PMS) system for the removal of sulfamethazine (SMZ) from water. The research results show that the addition of NTA increases the soluble iron content and the decomposition rate of PMS. Additionally, different inorganic ions, such as Cl-, have been found to affect the degradation of SMZ. In actual water bodies, the PMS/Fe0/NTA system can degrade SMZ up to 79.36%. Toxicity tests demonstrate a decrease in the inhibition rate of luminescent bacteria after degradation.

Summary: This study systematically investigated the mechanisms and key factors of p-nitrophenol (PNP) removal by biochar (BC) and sulfide double-modified nanoscale zero-valent iron (nZVI). The results showed that the residence time of the hydrothermal carbonization of waste bamboo chopsticks was the key factor affecting the removal of PNP by nZVI/BC. Biochar loading and surface sulfidation can enhance the reactivity and stability of nZVI, making it a more effective reducing agent for PNP removal.

The addition of light and the modified ZVI-Si/PS system improved the degradation performance of tetracycline. The optimal operating parameters were determined by response surface methodology, and the degradation pathway and mechanism were explained. Tetracycline degradation was influenced by the presence of inorganic ions and dissolved organic matter in different matrices.

Summary: Intense industrialization has increased the risk of metal leaching into groundwater in heavily polluted industrial sites. This study investigated the dissolution of Zn, Ni, and Cu in soil from a heavily contaminated industrial site during a flooding-drainage period. The results showed a steady decrease in metal solubility during both reduction and oxidation stages. Metal release was largely regulated by abiotic reactions rather than biotic reactions due to high metal concentrations and weak microbial effect in the industrial soil.

Summary: Chlorophenols (CPs) are considered priority control pollutants due to their high toxicity and wide distribution. The In-situ monitoring technique using diffusive gradients in thin films based on porous beta-cyclodextrin polymers (CDP-DGT) can stably monitor four typical CPs in water and soils. The study shows that the higher the soil organic matter content, the more CPs are distributed in the soil solid phase.

Summary: This study investigates the thermodynamic and kinetic effects of citric acid (CA) on the adsorption of Cd(II) and Ni(II) on goethite. The results show that CA enhances Cd(II) adsorption but inhibits Ni(II) adsorption. The adsorption of Cd(II) is faster in the presence of CA, while CA leads to the dissolution of adsorbed Ni(II) due to higher complexation constants. These findings have implications for understanding ion partition in the soil environment.

Summary: Soil Cd contamination is a major concern for wheat and food safety. This study investigated the key factors affecting Cd accumulation in wheat and developed predictive models. The results showed that Zn was the primary factor inhibiting Cd uptake in wheat. Models were developed to predict Cd contents in wheat tissues based on ion concentration, and a geochemical multi-surface model (MSM) was used to predict available Cd contents in soil. The combination of the hydroponic accumulation model and MSM provided good predictions of wheat-Cd. The findings of this study have implications for soil remediation and safe wheat production.

Summary: This study comprehensively compared the adsorption performance of two polar microplastics (polyamide and polyvinyl chloride) for antibiotic contaminants tetracycline and ciprofloxacin affected by heavy metals copper and cadmium. The presence of copper significantly improved the adsorption of antibiotics, while the presence of cadmium reduced the adsorption of ciprofloxacin. The findings highlight the dominant role of heavy metal-mediated complexation effects in antibiotic adsorption by microplastics.

Summary: This study investigates the Zn isotope fractionation on birnessite caused by adsorption reactions under different reaction times, pH values, and Zn concentrations. The results show that at pH 3-5 and Zn concentrations of 0.05-0.3 mM, the isotopic fractionation (D66Znadsorbed-aqueous) is around -0.46 +/- 0.04%, and gradually increases to -0.09 +/- 0.05% at pH 6-8 and Zn concentrations of 0.2 mM. The distinct isotopic fractionation of Zn is related to the differences in Zn local structure at different reactive sites of birnessite, including external edge sites and interlayer vacancies.
