摘要

Im mixed industrial effluent the presence of metal ions can retard the destruction of organic contaminants and the efficiency of recovery of metal is reduced by the presence of the organic species.Results are presented for a copper-ethylenediainetetra-acetic acid (EDTA) system in which both effects occur.An electrochemical cell alone can be used to recover copperin pH arange 1.5-4.5 but is not capable of achieving complete mineralisation of EDTA by anodic oxidation.A photlytic cell alone can achieve the destruction of EDTA by at pH 3.5 but leaves copperin solution.A combined photolytic-electrochemical system using an activated carbon concentrator cathode achieves the rapid simulataneous destruction of EDTA and recovery of copper.
