Description
Summary:The electrochemical and photoelectrochemical oxidation of C.I. Acid Violet 1 using a titanium electrode coated with a mixture of TiO 2 and RuO 2 was investigated. Cyclic and differential pulse voltammetry was used to determine the kinetics of the process. Oxidation parameters such as current intensity, temperature, anode surface, pH and time were optimized. The combined electrochemical and photochemical oxidation of C.I. Acid Violet 1 increased the effectiveness of dye conversion to 57% based on TOC.
