Novel heterogeneous Fenton catalysts prepared using electrolytic manganese residue for efficient degradation of acetaminophen.

ABSTRACT: Electrolytic manganese residue (EMR) was used as a support to prepare novel EMR-supported catalysts for the heterogeneous Fenton degradation of acetaminophen. Among the five supported catalysts, Co/EMR showed the highest catalytic activity. Several important factors influencing the decay of acetaminophen, including Co loading content, catalyst dosage, H₂O₂ concentration and initial solution pH, were investigated. Under optimal experimental conditions, acetaminophen degradation rate and the TOC removal efficiency reached 63.8% and 35.7% within 480 min, respectively. Free radical quenching and EPR analysis showed that the high catalytic degradation rate of acetaminophen could be ascribed to the presence of ˙OH and O₂˙^-. Based on the XPS analysis, t
