Summary: This study improved the reactivity of zero-valent iron (ZVI) towards tetracycline (TC) degradation by using biogenetic sulfidation and biochar loading. Biochar provided more attachment sites and alleviated ZVI agglomeration. Biogenetic sulfidation inhibited ZVI surface passivation. The formation of Fe(II/III)-TC complexes promoted TC degradation.

Summary: A core-shell structure of sulfidated nanoscale zero-valent iron deposited on biochar (S-nZVI/BC) was synthesized and proved to be highly reactive and selective for tetrabromobisphenol A (TBBPA) degradation compared to nZVI/BC. The combination of sulfidation and biochar enhanced the reactivity and selectivity of S-nZVI/BC by controlling the distribution of sulfur species and improving hydrophobicity and electron-transfer. The mechanism investigation revealed that core properties dominated reactivity and TBBPA debromination involved direct electron-transfer.

Summary: The study found that sulfidated ZVI is more effective in immobilizing As(V) in soil compared to unamended ZVI. To achieve good As retention performance, sulfidated ZVI should be fully mixed with the soil or located on the downstream side of As migration. The findings provided insights into ZVI remediation of As(V)-polluted soil.

Summary: The sulfidation of microscale zero-valent iron particles (S/mZVI) has been widely recognized as a method to improve reactivity and selectivity. In this study, different types of nickel-sulfidated composite mZVI particles were synthesized by adjusting the sequence of nickel doping and sulfidation. The reactivity and selectivity towards atrazine in groundwater were compared, and the underlying mechanisms were investigated. The results showed that Ni/S-mZVI exhibited higher removal rate of atrazine and reduced hydrogen accumulation compared to S/mZVI. The enhanced removal rate was attributed to the generation of atom hydrogen and direct reduction mediated by electron transfer. Meanwhile, the reduced hydrogen evolution reaction in Ni/S-mZVI can be explained by the involvement of Fe oxides. Overall, the bimetallic modification of S/mZVI is a promising strategy for groundwater remediation.

Summary: This study systematically investigated the effect of NO3- on the degradation of TCE by S-ZVI and its mechanism. The results showed that NO3- did not affect the degradation pathway of TCE, but at high concentrations, it competed for electrons and led to an increase in the production of acetylene. Additionally, the presence of NO3- promoted the formation of Fe3O4, which improved the degradation efficiency of TCE.

Summary: Sulfidated zero-valent iron (SZVI) samples were synthesized using different sulfur precursors, resulting in increased surface area and hydrophobicity. SZVI-Na2S showed the highest specific surface area and optimal hydrophobicity. Sulfidation also improved the corrosion potential and Fe0 content of SZVI. In terms of Cr(VI) removal, SZVI-Na2S exhibited the highest efficiency through enhanced adsorption, rapid reduction, and precipitation.

Summary: This study investigated the synchronous activation of H2O2 and persulfate by sulfidated zero valent iron in ambient conditions for Fenton-like oxidation of bisphenol S. The activation of sulfidated zero valent iron induced H2O2 or persulfate could be greatly enhanced with the assistance of persulfate and H2O2, respectively, even across a wide range of pH value. The study demonstrated that the system could be a more efficient, advanced oxidation technology capable of being used across a broad pH range for the degradation of emerging pollutants.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
