In this study Co:Mn3(PO4)2·3H2O(CoMnP-10) catalytic material was prepared by chemical precipitation method, and the morphological structure of the catalyst was optimized by the characterization analysis that Co was uniformly distributed in Mn3(PO4)2·3H2O. Experiments results indicated that the CoMnP-10/PMS system demonstrated outstanding degradation capability towards SDZ, and under the optimal conditions (catalyst dosage of 20 mg, PMS concentration of 0.27 mM, and pH at 5.1), 96% removal of pollutants could be achieved within 3 min. The active species involved in the reaction (SO4−•, •OH, 1O2 and O2−•) in the CoMnP-10/PMS system were identified by free radical bursting experiments and EPR tests, and the incorporation of Co boosted the electron transfer rate, promoted the Co/Mn dual-metal redox cycling, and thus improved the degradation efficiency of SDZ. According to the above - mentioned research, a reasonable catalytic mechanism for the degradation of SDZ in the CoMnP-10/PMS activation system was proposed.
