ABSTRACT
In this experiment, Rhodamine B (RB) wastewater was treated by a double-cathode electrochemical method. The effects of RB concentration, electrode distance, current, and electrolyte concentration on the decolorization rate of RB were discussed. The results showed that when the electrolysis time was 60.0 minutes, the concentration of RB wastewater was 0.1000 g/L, the electrode distance was 2.0 cm, the electrolyte concentration was 0.10 mol/L NaCl, the current intensity was 0.50 A, and the aeration rate was 1.20 L/min, the decolorization rate of RB could reach 96.94%. The use of a double-cathode system in this work results in a high decolorization rate, indicating a new direction for developing high-performance advanced oxidation technology for the treatment of refractory organic compounds.
