Synthesis of an Environmentally Friendly Modified Mulberry Branch-Derived Biochar Composite: High Degradation Efficiency of BPA and Mitigation of Toxicity in Silkworm Larvae.

ABSTRACT: In the present study, mulberry branch-derived biochar CuO (MBC/CuO) composite was successfully synthesized and used as a catalyst to activate persulfate (PS) for the degradation of bisphenol A (BPA). The MBC/CuO/PS system exhibited a high degradation efficiency (93%) of BPA, under the conditions of 0.1 g/L MBC/CuO, 1.0 mM PS, 10 mg/L BPA. Free radical quenching and electron spin-resonance spectroscopy (ESR) experiments confirmed that both free radicals ^•OH, SO₄^•- and O₂^•- and non-radicals ¹O₂ were involved in the MBC/CuO reaction system. Cl^- and NOM displayed negligible influence on the degradation of BPA, while HCO₃^- promoted the removal of BPA. In addition, the toxicity tests of
