Persulfate activation by biochar and iron: Effect of chloride on formation of reactive species and transformation of N,N-diethyl-m-toluamide (DEET)

•Biochar/Fe(III)/persulfate effectively degrades N,N‑diethyl-m-toluamide (DEET).•SO4•− are the dominant reactive species in the biochar/Fe(III)/persulfate system.•Chloride shifts the reactive species from SO4•− to •OH and to chlorine species.•PMSO is not a selective indicator for Fe(IV) in persulfat...
