Nonmetallic doped biochar showed great potential for activating persulfates, gaining considerable attention in environmental remediation. However, its activating mechanism and phytotoxicity remain unclear. Herein, a novel B-doped biochar (BBC) was synthesized using waste tea residue and boric acid to activate ammonium persulfate (APS) for efficient degrade quinclorac (QC) in irrigation water. BBC exhibited remarkable catalytic performance for APS, achieving a QC removal efficiency of 91% within 30 min under optimal conditions (0.5 g·L -1 BBC a...
