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 was achieved showing that CWPO can
be recognised as an attractive wastewater techonology for removal
of azo dyes. In Fig. 10, the results of the experiments performed are
plotted.
