Abstract

The electrochemistry method was applied for the treatment of high-salinity dye intermediate wastewater from the process of 3-diethylaminophenol. The results indicate that CODcr and color removal rate can reach 70% and 80% respectively under the optimum electrolysis conditions (electrical current density=0.015A/cm2, electrolysis voltage=8.4V, t=90min). The primary mechanism of electrochemical reaction was also studied by investing the treatment of dye effluents containing NaCl and Na2SO4.
