摘要：
Bisphenol A (BPA) was regarded to conduce to the puberty symptoms of mammalian species. Moreover, BPA is quite recalcitrant to bio-degradation and easily accumulate in the ecological system. Hence, it is still a serious challenge to develop the novel and efficient methods for the removal of BPA. Herein, Zn-doped OMS-2 catalyst (Zn-OMS-2) has been successfully synthesized, by pre-incoporation method, for degradation of bisphenol A via perdisulfate (PDS) activation. The experiment results shown that the Zn-OMS-2 exhibited superior degradation efficiency than that of OMS-2 in BPA degradation. Based on Arrhenius equation, the activation energy (Ea) of BPA degradation was found to be 7.43 kJ/mol. Free radical quenching experiment and EPR result demonstrated that 1O2 was the major reactive oxygen species in the Zn-OMS-2/PDS system.
