Abstract
In the present investigation, a novel rotating disc electrochemical reactor has been developed to treat Methyl Orange dye effluent. Stainless steel and ruthenium oxide‐coated titanium electrodes were used as cathode and anode, respectively. A statistical tool of the Box–Behnken method has been used to design the experimental run and optimisation. The combined effect of the operating parameter on the efficiency of the process has been critically examined. A quadratic model for reduction of chemical oxygen demand has been developed. A maximum of 96% chemical oxygen demand removal was observed under optimum conditions. The degradation mechanism was studied by ultraviolet–visible spectrophotometer, Fourier Transform–infrared and high‐performance liquid chromatography. From the present investigation, it has been observed that dyehouse effluent can be effectively treated using the novel electrochemical reactor.Keywords
