Compound-Specific Isotope Analysis Reveals Sulfidation-Induced Mechanistic Shifts during Decabromodiphenyl Ether Debromination by Nanoscale Zero-Valent Iron.
Sulfidated nanoscale zero-valent iron (S-nZVI) is widely used for reductive dehalogenation, yet how sulfidation alters the reaction mechanism of highly halogenated contaminants during multistep transformation remains poorly understood. Here, BDE-209 debromination by S-nZVI across a range of S/Fe molar ratios was invest...
