Synergistic effects of H₂O₂ on the performance of nano-zero-valent manganese biochar (nZVMn/PBC) for the treatment of chlorpyrifos from aqueous solution.

ABSTRACT: This study explores the efficient degradation of the highly toxic organophosphorus pesticide chlorpyrifos (CPY) from aqueous solution using a novel nano-zero-valent manganese-decorated plant biochar composite (nZVMn/PBC). The composite was synthesized via a chemical reduction method and thoroughly characterized using FTIR, XRD, SEM, TEM, EDS, XPS, and BET analyses. Characterization results revealed that nZVMn/PBC possessed a highly porous and crystalline structure enriched with abundant functional groups, favorable for catalytic degradation. Under optimized conditions ([CPY]₀ = 9 mg L^-1, [nZVMn/PBC]₀ = 25 mg L^-1, reaction time = 90 min), the composite achieved 84% degradation of CPY. Remarkably, the introduction of H₂O₂
