Abstract |
The aim of the present study is to degrade Malachite green (MG) dye electrochemically, which is become an alternative attractive method in recent years. The degradation of dye was studied in KCl as supporting electrolyte medium at graphite anode and platinum cathode under amperostatic condition. The variation of the dye concentration was accessed by UV-Visible measurements and Chemical oxygen demand (COD) reductions were also performed. The results clearly shown that at the optimum conditions(current density = 1.805 mA cm-2, initial dye concentration = 100 mgL-1, KCl concentration = 5 gL-1, Temperature = 25 ± 2 °C, pH = 4, electrode gap = 1 cm), 99% MG degradation and 82% of reduction in COD was achieved within 120 min during electrolysis with maximum energy resource management, i.e., 21.212 KWh kg-1. The reaction mechanism of electrocatalytic MG degradation was characterized with mass spectrum and Fourier transform infrared spectroscopy (FT-IR). Kinetic studies showed that at different initial dye concentration degradation takes place through a first order diffusion controlled reaction. The study showed that electrochemical oxidation is a superior technology for treatment of Malachite green with maximum power management after 120 min of electrolysis treatment. |
