PENGARUH VARIASI JARAK ELEKTRODA PADA SEL ELEKTROKIMIA UNTUK MENDEGRADASI LINDI DENGAN TEKNIK ELEKTROOKSIDASI ELEKTROKOAGULASI
The purpose of this paper is to determine the most effective distance between electrodes to degrade leachate by electro-oxidation electrocoagulation technique. Leachate TPS Bengkala has COD content of 38763 mg / L, 0 mg / L DO, 0 mg / L COD, pH 9, and absorbance 17.1. Furthermore, 50 mL of leachate was degraded by electro-oxidation electrocoagulation technique on variation of distance between electrodes. Variation of distance between electrodes are used 3 cm, 6 cm, 9 cm, and 12 cm. Electro-oxidation electrocoagulation techniques were performed using two carbon electrodes and two aluminum electrodes. The electrode part was immersed 2 cm into a 50 mL mixture of leachate waste and 10 mL of sea water at a voltage of 5 volts. After 0.5 hours the electric current was disconnected. The result of electro-oxidation electrocoagulation was then measured DO by DO meter, COD and absorbance was measured by UV vis shimadzu, pH with pH meter, and BOD. Leachate measurements after electro-oxidation electrocoagulation showed that the most effective distance between electrode degradation leachate that is at 3 cm distance, with the value of DO 3.52 mg / L, COD 428 mg / L, BOD 3.02 mg / L, absorbance 0, 23, and pH 7.8.
