Study on the Electrochemical Oxidation of Polycyclic Pollutants

In this study, electrochemical method was used to treat Rhodamine B (RB) wastewater. This paper discussed the influence of electrolysis time, voltage, electrolyte concentration and wastewater concentration on the decolorization rate of RB. The results showed that when the concentration of RB wastewater was 100.0 mg/L, 1.5 L, cathode was titanium mesh, anode was stainless steel mesh, electrode distance was 3.0 cm, 0.10 mol/L KCl was electrolyte, aeration volume was 1.20 L/min, voltage was 7.0 V, electrolysis time was 30.0 min, decolorization rate was 98.0%; the concentration wastewater was 150.0 mg/L, decolorization rate reached 95.49%.
