Abstract
The aim of the present investigation is to treat Evans blue dye effluent using tubular electrochemical reactor. The electrode is made of stainless steel and oxide coated expanded titanium as cathode and anode respectively. The cylindrical mesh type anode is fitted in the tubular electrochemical reactor. The effect of operating parameters such as current density; initial dye concentration; initial solution pH, recirculation flow rate and supporting electrolyte concentration has been studied on COD reduction. It can be observed from the present investigation that the electrode Ti/RuO0.3Ti0.7O2 effectively degrade the Evans blue dye effluent and the kinetics of Evans blue dye degradation follows the pseudo first order kinetics. Further, dispersion model has also been developed to determine the exit concentration of the effluent. The model simulation is compared with experimental value and it is observed that the model matches well with correlation coefficient of 0.98.
