Abstract

Copper doped ordered mesoporous carbon (Cu-OMC) was prepared by evaporation induced self-assembly and presented high catalytic activity for the activation of peroxymonosulfate (PMS).At the condition of catalyst dosage 0.1g/L, PMS concentration 0.5mmol/L,the removal of 20mg/L bisphenol A (BPA) could be achieved 91% in 60min.The reaction can be performed under a wide pH range around 3-11 and little influenced by anions including Cl^-,SO₄^2-,HCO₃^- and PO₄^3-.The reactive oxygen species (ROS) generated during the reaction process were analyzed by radical quenching tests and electron spin response (EPR).It was found that apart from sulfate radical (SO₄^·-) and hydroxyl radicals (·OH),singlet oxygen (¹O₂) also contributed to the degradation of BPA.

Key words： peroxymonosulfate sulfate radical ordered mesoporous carbon bisphenol
