Unveiling the Role of the Soil Matrix in Trichloroethylene Degradation by Ball-Milled Sulfidated Microscale Zero-Valent Iron

Abstract Ball-milled sulfidated microscale zerovalent iron (S-mZVIbm) is highly effective in degrading trichloroethylene (TCE) in anoxic water. This study investigated its performance and soil-mediated regulation in a soil-water mixed system (SWMS) using two natural soils. The re...

Sustained Fe3+/Fe2+ Cycling Enables Photochemical Defluorination of Perfluoroalkyl Carboxylic Acids via Ligand-to-Metal Charge Transfer

Abstract Per- and polyfluoroalkyl substances (PFASs) are widespread persistent pollutants that threaten environmental and human health. Although Fe3+-mediated ligand-to-metal charge transfer (LMCT) has been shown to promote PFAS photochemical defluorination, existing systems rely...

Tripolyphosphate-MediatedInterfacial Electronic ReconfigurationBoosts •OH Production and Redirects Mineral EvolutionDuring FeS Oxygenation

Abstract Oxygenation of mackinawite (FeS) at redox interfaces constitutes a key biogeochemical process that generates hydroxyl radicals (•OH) and facilitates contaminant attenuation. However, the influence of common inorganic ligands such as tripolyphosphate (TPP) on interfacial...
