Decolorization of Landfill Leachate Using Electrochemical Oxidation Technique

The study was carried out to investigate the electrochemical oxidation of landfill leachate from the Jeram sanitary landfill leachate using charcoal base metallic composite electrodes. The control parameters used were applied voltage, Cl- concentration (as supporting electrolyte) and pH of the solution. The optimum conditions obtained were NaCl concentration of 1.5 % (w/v), applied voltage of 10 V, operating time 180 min and (C60C15Co10PVC15)-Co-G electrode as an anode. Electrochemical treatment using charcoal base metallic composite electrode was able to remove color up to 79%.
