Mediated Electrochemical Oxidation (MEO) is one of electrochemical method are widely used to degrade organic pollutans from waters. Dyes represents one of the problematic group. We have studied the degradation of methylene blue (MB) using MEO methode by batch system with Ce (IV) as mediator. Ce (IV) as mediator was made electrochemically from the oxidation of Ce (III). Ce (IV) can degrade textile dye waste by oxidizing them into simpler products so that the danger level is reduced. Voltammetric studies have been performed by the cyclic voltammetric technique using carbon paste electrodes as working electrodes, Ag/AgCl as comparative electrodes and platinum wires as auxiliary electrodes. The results show the potential of oxidation of Ce (III)/Ce(IV) and methylene blue at 1.25 volts and 0.27 volts. The study of methylene blue degradation was performed by electrolysis using platinum wire as anode and cathode. The total degradation...
