Summary: Mechanochemical (MC) remediation using zero-valent iron (ZVI) as co-milling agent can effectively dispose solid halogenated organic pollutants (HOPs). Incomplete dechlorination is a common challenge. This study investigates a reduction-oxidation coupling strategy using ZVI and peroxydisulfate (PDS) as co-milling agents, achieving higher dechlorination ratio and mineralization efficiency for 2,4-dichlorophenol (2,4-DCP) through the accumulation of SO4 ·-. The necessity of coupling reduction with oxidation in MC destruction for solid HOPs is validated.

Summary: In this study, it was demonstrated that ionic solutions of Me-chloride can accelerate the sulfidation of mZVI by S0, with Mg2+ being the most efficient in depassivating the mZVI. The synthesized S-mZVIs exhibited high reduction capacity and inhibited the formation of cis-1,2-dichloroethylene, making them a promising tool for sustainable remediation of contaminated sites.

Summary: The study demonstrated that ZVI effectively degrades CCl4, with approximately 75% transformed into chloroform through hydrogenolysis. The rate of chloroform transformation was slower compared to CCl4, leading to chloroform accumulation. CCl4 degradation is a pseudo first-order process and the ZVI dosage significantly affects the degradation efficiency.

Summary: Electric field assisted remediation using nano iron has shown significant results and economic benefits during pilot applications. This method is based on donating electrons to zero-valent iron with strong reductive capacity. Experimental results demonstrated the generation of ethene and ethane near the anode due to the presence of dissolved Fe2+ ions.

Summary: The study found that nFe(0) undergoes transformation during the reaction with chloro-organics, resulting in the formation of different iron oxides, and 2,4-DCP is rapidly dechlorinated to 2-CP, 4-CP, and phenol. Without the support of Ni and attapulgite, the transformation of nFe(0) and dechlorination of 2,4-DCP were not significantly achieved.

Summary: This study investigated the reactivity of nickel/zero-valent iron (Ni/Fe) during the dechlorination of PCB-99 at different temperatures. Results showed that as the temperature increased, Ni/Fe was oxidized heavily, reducing the electron density of Fe(II) and inhibiting electron transfer. The main dechlorination pathway followed the order meta- > para- > ortho-position, which could be explained by the lowest unoccupied molecular orbital (LUMO). Overall, this work improves our understanding of the dechlorination behavior of PCB-99.

Summary: This study evaluated the effects of sulfidation and emulsification treatment on the performance of nanoscale zero-valent iron in the reductive dechlorination of trichloroethylene (TCE) in groundwater. The sulfidized and emulsified zero-valent iron (S-EZVI) can sequestrate unreacted TCE and reduce the corrosion of iron. The electric-field-enhanced S-EZVI technology showed improved performance in removing TCE under different pH conditions.

Summary: Ball milling is effective in activating and reducing the size of microscale zero valent iron (mZVI) and sulfidating mZVI mechanochemically. However, there are differences in the interaction between chlorinated ethenes (CEs) and ball milled mZVI (mZVIbm) and mechanochemically sulfidated mZVI (S-mZVIbm) that are not well understood. This study found that simple ball milling exposed active Fe0 sites, while mechanochemical sulfidation decreased Fe0 sites and increased S2 sites. The sulfidation process enhanced the reactivity of TCE dechlorination the most, followed by PCE and 1,1-DCE, but reduced the reactivity of trans-DCE, cis-DCE, and VC compared to simple ball milling. Sulfidation also improved the electron efficiency of CE dechlorination, except for cis-DCE and VC. The kSA of cis-DCE, VC, and trans-DCE dechlorination positively correlated with the sulfide content.

Summary: Electron efficiency (ee) of Pd-nZVI and S-nZVI was systematically explored and compared in this study. It was found that the ee of Pd-nZVI increased and then decreased with [Pd/Fe], while that of S-nZVI increased with [S/Fe]. The variables of TCE concentrations, pH solution, aging time, and water matrices also affected the ee of both materials.

Summary: Organic cosolvents are commonly used to enhance the dissolution of poorly water-soluble organic pollutants into aqueous solutions for environmental remediation. This study investigated the effects of five organic cosolvents on the degradation of hexabromobenzene (HBB) catalyzed by montmorillonite-templated subnanoscale zero-valent iron (CZVI). The results showed that all cosolvents promoted HBB degradation, but to different extents, which were influenced by the properties of the cosolvents, such as viscosity, dielectric constant, and interactions with CZVI.

Summary: This study found that with sodium acetate as the organic carbon source in the zero-valent iron-mediated nitrogen removal system operated in co-substrate mode, the removal efficiency of NH4+-N and TIN could be significantly improved. The organic matter not only stimulated the activity of ammonia oxidation and denitrification, but also reduced the toxicity of iron to microorganisms, leading to the enrichment of certain bacteria.

Summary: This study investigates the use of zero-valent iron activated peroxidized sulphate (ZVI/PDS) synergistic action for the effective removal of EDTA-chelated copper. The results show that the ZVI/PDS process significantly improves the removal efficiency of complexed copper and total organic carbon compared to ZVI alone. Factors such as the molar ratio, initial pH, ZVI dosage, and PDS dosage influence the removal efficiency of complexed copper. Analysis indicates that the method can reduce chelated copper and immobilize it on the ZVI surface.

Summary: Membrane distillation, an emerging desalination technology, has great potential for treating high-salinity industrial wastewater. However, the wetting of hydrophobic membranes has posed a major challenge. In this study, an omniphobic membrane was prepared by growing nano-ZnO needles on a PVDF membrane surface, followed by fluorination. The modified membrane exhibited superior antiwetting properties and high salt rejection, making it promising for treating high-salinity wastewaters containing surface-active substances.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
