摘要：
Aiming at the produced waster containing polyacrylamide(PAM), the heterogeneous Co3O4-GO/PMS system was selected to degrade PAM in this paper. The characteristic of Co3O4/GO are studied. The degradation experiment shows that Co3O4/GO was successfully prepared and exhibited satisfactory degradation efficiency. The removal efficiency can exceed 99.7% within 90 min. Furthermore,the degradation effect of PAM was better in acidic and neutral solutions. Based on the quenching experiments, SO4-. and .OH are the main active radicals in Co3O4-GO/ PMS system. PMS is activated by mental ion and generated SO4-. to remove PAM. After 5 runs of reuse, PAM degradation efficiency still exceeded 95.7%.
