MEDIATED ELECTROCHEMICAL OXIDATION USING COBALT (III) AS MEDIATOR FOR ORGANIC COMPOUND DESTRUCTION Herlina1, Derlini2 1.Department of Electrical Engineering, 2. Department of Industrial Engineering, Faculty of Industrial Technology, Institute Technology of Medan, North Sumatra, Indonesia e-mail: ABSTRACT Organic waste treatment has been developed widely with electrochemical methods, because has advantages of low cost and efficient, the exhaust gas does not contain toxic materials and hazardous waste and the temperature of secondary treatment process is relative low. Electrochemical oxidation of organic compounds using metal ion mediator is one alternative method that is appropriate for the management of organic waste.…show more content…
So that the electrochemical oxidation process, improving the metal oxidizer ingredient in acid medium will increase, if the concentration of the acid medium increased and decreased with increasing temperature. Oxidation of Organic Compounds Organic compounds are oxidized in this case is a phenol compound and ethyleneglycol compound. In the electrochemical oxidation of organic compounds with the mediator Co (III) will produce carbon dioxide gas CO2 and water, according to the following chemical reaction: 28 Co3 + (aq) + C6H5OH (aq) + 11 H2O (aq) ------- 6 CO2 (g) + 28 Co2 + (aq) + 28H + (aq) 10 Co3 + (aq) + (CH2OH) 2 (aq) + 2H2O (aq) ------- 2CO2 (g) + 10 Co2 + (aq) + 10 H + (aq) Carbon dioxide liberated during the oxidation reaction of organic compounds supplied by a hose to a solution of Ba (OH) 2 will form a precipitate BaCO3 segingga in accordance with the following…show more content…
At 6 Volt potential, with 4 M nitric acid concentration and temperature of 25 ° C as much as 23.86% Co (II) is converted to Co (III) within 2 hours of the initial concentration of Co (II) 0.1 M. The addition of AgNO3 to catholyte can increase the concentration of Co (III). At the optimum conditions, the mediator metal ion CO (III) has been successfully mendestruksi by 66.44% and 86.47% phenolic compounds ethyleneglycol compound electrochemically oxidized to CO2 for 2 hours with the initial concentration of each organic compound of
