The degradation rates as high as 99%, with a high decolorization ratios of 96 8% and TOC concentration reduction of about 80 5% were observed during a period of 30 min in presence of both photocatalyst and filler electrodes. The kinetics of electrochemically assisted photocatalytic degradation of direct sky blue was also investigated.展开更多
