Abstract

A silver mediated electrochemical oxidations is a promising technique for the destruction of organic compounds. The destruction of 30%tributyl phosphate in dodecane in a nitric acid medium containing electrogenerated Ag(II) to carbon dioxide was studied by using a laboratory scale electrochemical oxidation cell. The electrolyte used in this system was 0.5 M AgNO3 in the range of 3 - 7 M HNO3, at operating temperatures of 60ºC ± 5ºC, under ultrasonic agitation and the output of a DC power supply at constant the current was 60 A, respectively. Electrolysis was carried out for 5 hours. The results show that, in silver mediated electrochemical oxidation method, destruction of 30%TBP/Dodecane was increased with increase of concentration of HNO3.
