Abstract

Charcoal powders obtained from commercially available charcoal and the open burning of palm oil, rubber, coconut, and mangrove trees were used to fabricate composite electrodes in this study. A weight portion of charcoal powder, graphite, cobalt, and polyvinyl chloride (C-CG-Co-PVC) were mixed in tetrahydrofuran (THF). The fabricated composite electrodes were then used as working electrodes for the electrochemical treatment of landfill leachate samples. A variable pressure scanning electron microscope (VPSEM) was used to examine the appearance of the charcoal powder. The results showed that rubber tree charcoal powder is the best charcoal powder for fabricating the composite electrodes, as it has various pore sizes and more surface area available for adsorption and reaction. Field emission scanning electron microscopy (FESEM) was performed before and after electrolysis of the landfill leachate. The results revealed that the presence of voids on the electrode surface before and after electrolysis improved the electrochemical oxidation of the landfill leachate, and yielded removal percentages in colour, COD, NH3-N, and total P of not less than 80%, 91%, 73%, and 84%, respectively.
