Abstract

The trypan blue (TB) dye synthetic wastewater was treated in presence of chloride ions by electrochemical method. The effect of current density, pH, initial concentration of dye and supporting electrolyte on color and COD removal were investigated. The UV-Vis ab­sorption intensity, chemical oxygen demand (COD), cyclic voltammetry (CV), Fourier transform- infrared spectroscopy (FT-IR), gas chromatography – mass spectrometry (GC-MS) analysis were conducted to investigate the kinetics and degradation pathway of TB dye.
