Indirect Anodic Oxidation Applied for the Treatment of Simulated Wastewater Containing Reactive Dyes

Abstract:

The treatment of simulated wastewater containing reactive dyes was carried out by indirect anodic oxidation with Ti/IrO₂ electrode. The influences of pH value, voltage, electrolysis time and NaCl dosage on the degradation performance were studied. The results show that under the condition (pH=3, voltage=20V, NaCl=2.5g/L), for reactive orange X-GN and yellow X-R, their solutions almost complete bleach after being treated for 30 min, and the removal rates of COD is 68% after being treated for 60 min; for reactive black KN-B, decolorization rate is up to 100% and the removal rate of COD reaches 60% after being treated for 60 min.
