Research on Degradation of Reactive Brilliant Blue KN-R by Cu_2O Fenton-like

Fenton-like system composed by Cu2O and H2O2 has very good oxidation and degradation effect to organic matter in printing and dyeing wastewater.Cu2O Fenton-like was applied to oxidate and degrade reactive brilliant blue KN-R in the experiment.Research showed good results.When initial pH of KN-R solution was 2,water bath temperature was 50 ℃,and KN-R solution(50 mL,100 mg/L) was treated by Cu2O(0.429 g,0.3 mmol) and H2O2(0.1 mL,30%) for an hour,the decoloured rate was 95.09% and the removal rate of TOC was 56.38%.
