Degradation of malachite green dye by using a voltage source potential and certain current is passed throughcarbon/TiO2 electrodes as anode and silver electrodes as cathode has been developed in this research. Degradation with variation of potential, pH and time is performed into solution of malachite greencontaining electrolytes support 0.1 M NaCl. Results of this analysis obtained optimum conditions of pH 7-8 and potential 10 V at degradation time for 15 minutes. Based on the voltammogram, reactions that occur are electrochemical-chemical-electrochemical (E-C-E) and irreversible This method can reduce the COD value up to 81.89% and 100% degrade malachite green solution at 25 ppm during 30 minutes. The result of analysis show that malachite greenis degraded and produce CO2.
