| dc.description | Electrochemical oxidation technique which has high efficiency in organic pollutants degradation and ammonia removal has been applied to treat a landfill leachate which contains organic and inorganic pollutants in high concentration. In this study, a charcoal base metallic composite electrode which is low in cost and effective to treat landfill leachate by electrochemical oxidation technique has been fabricated. The charcoal base metallic composite electrode was prepared by mixing together a weighed portion of charcoal, graphite and metals powder in different composition percentage with poly vinyl chloride (PVC) as a binder in 4 mL tetra hydrofuran (THF) which act as a solvent. Metals used in the preparation of the electrodes are Ag, Al, Co, Cu, Ni and Fe. The results show that the mixture of commercially available charcoal, graphite, Co and PVC at a composition of 60:15:10:15 (w/w), known as C60CG15Co10-PVC15 electrode gives the highest value of color removal and good mechanical strength. Optimization of the operating parameters in landfill leachate electrolysis using C60CG15Co10-PVC15 electrode was carried out to maximize the decolorization and removal of chemical oxygen demand (COD) of the landfill leachate. The results obtained show that under the optimum operating conditions, sodium chloride (NaCl) concentration of 1.5 % (w/v) as supporting electrolyte, applied voltage of 10 V, operating time of 120 min and at pH 4, C60CG15Co10-PVC15 electrode as an anode and stainless steel as a cathode able to remove color and COD at 74 and 89 % respectively. Several sources of charcoal powder obtained from commercially available charcoal and charcoal prepared form palm oil, rubber, coconut and mangrove trees were also tested. The results showed that charcoal form rubber tree was the best electrode which gave the removal percentage of color and COD at 80 and 91 % respectively. Later, surface morphological study was performed on the electrode fabricated from charcoal obtained from rubber tree using Field Emission Scanning Electron Microscopy (FESEM) before and after electrolysis of the landfill leachate. FESEM micrograph shows the presence of voids on the electrode surface before and after electrolysis of leachate sample which able to improve the electrochemical oxidation of landfill leachate. A Variable Pressure Scanning Electron Microscope (VPSEM) was used to examine the appearance of the charcoal powder. Results of the VPSEM analysis showed that rubber tree charcoal powder is the best type due to the many holes and more surface area available for adsorption and reaction. The characterization of landfill leachate was then examined using parameters such as color, chemical oxygen demand (COD), ammonia (NH3-N), total- P (PO4-3), total suspended solid (TSS) and pH. The study shows decreasing value of color, COD, NH3-N and P (PO4-3) after electrolysis of landfill leachate using CRUBBER TREE60CG15Co10-PVC15 electrode.,Master / Sarjana | |
