In the study, the experiments were performed
under the optimized conditions for the CWPO of the mixture of
Reactive Black 5 and Procion Red MX-5B. These conditions were 0.5 g/L activated carbon loading, 2mL H2O2/300mL dye solution,
a pH=3 and T=80◦C. The reaction time was 120 min. Under these
conditions, 93% dye removal
