摘要

Electrochemical oxidation is being increasingly considered in recent years as a technique to destroy organic compounds in industrial waste. Johnson studied the anodic oxidation of HEDTA on platinum in acid sulfate solutions. Polarizations relationships were obtained and numerous reactions products were identified that indicated a sequential removal of acetate groups from the EDTA. The initial decarboxylation was followed by a reverse Schiff-type reaction which produced formaldehyde and the corresponding amine. The purpose of this investigation was to determine if tetrasodium ethylenediaminetetraacetic acid (Na(sub 4)EDTA) could be oxidized on platinum in alkaline solutions and to obtain information about the electrochemical reaction kinetics necessary to model the electrochemical destruction of Na(sub 4)EDTA in alkaline solutions.
