a Degradation efficiencies of SMX in different reaction systems. (Conditions: [Catal.]0 = 0.1 g L−1, [PMS]0 = 0.15 mM, [PAA]0 = 0.18 mM, [pH]0 = 6.3, [SMX]0 = 10 mg L−1, [Temp.]= 20 ± 2 °C). b Comparison of degradation efficiencies and reaction rate constants of different reaction systems. c Comparison utilization efficiencies of PMS and PAA by CoSAs-ZnO. d Evaluation of SMX removal using CoSAs-ZnO/PMS and CoSAs-ZnO/PAA systems with six cycles. e pH changes of CoSAs-ZnO/PMS and CoSAs-ZnO/PAA reaction systems under different initial pH conditions. f Degradation efficiencies of SMX by CoSAs-ZnO/PMS and CoSAs-ZnO/PAA systems at different initial pH. g TOC removal efficiencies by different reaction systems. h Removal of multiple pollutants by CoSAs-ZnO/PMS and CoSAs-ZnO/PAA reaction systems. i Effect of background ions on the efficiency of SMX degradation by CoSAs-ZnO/PMS and CoSAs-ZnO/PAA reaction systems. The error bars represent the standard deviation of three replicate tests.
