Abstract


Abstract:The electrochemical behaviour of methylene blue (MB) was studied in a single compartment cell with Ti/Pt anode. Experiments were carried out to investigate the influence of: current intensity (0.05 - 0.4 A), MB concentration (5 - 20 mg/L), initial pH (4 - 11) as well as electrolyte concentration (0.025 - 0.1 M NaCl) on the kinetic of MB degradation over a Ti/Pt electrochemical process. The results show that the removal rate is favoured in acidic medium and at increased both electrolyte concentrations and current densities. A complete colour removal of 10 mg/L MB solution is achieved within 35 min at optimal current intensity of 0.4 A with 0.1 M NaCl electrolyte solution at inherent pH. The decomposition follows a pseudo-first order kinetic where the removal rate is independent of MB initial concentration.
