Studies on Treatment of Simulated Printing and Dyeing Wastewater on Titanium Electrode Coated MnO₂ Doped with Ce

Abstract:

Experiments on treatment of simulated printing and dyeing wastewater by prepared titanium-based electrode coated manganese dioxide doped with cerium were carried out in this paper. Factors such as current density, electrolyte concentration, solution pH value, electrolysis time, initial concentration of simulation printing and dyeing wastewater on the effect of treatment were also investigated. It is showed that: utilizing the self- prepared electrode to treat printing and dyeing wastewater in optimized conditions, which current density is 30mA/cm2, electrolyte (sodium chloride) concentration is 0.1 mol/L, electrolysis time is 80min, and pH is 9, 92% and 97% of CODcr and color removal were achieved, respectively.
