Enhanced degradation of some refractory pollutants from industrial effluents by electrochemical processes

Abstract

The project dealt with the preparation and activation of dimensionally stable anodes (DSA) based on non-noble metal oxide films in order to minimise costs. The study of electrochemical behaviour of DSA in the presence of ethoxylated nonyl-phenols was carried out by cyclic voltammetry. DSA were tested as part of the degradation of ethoxylated nonylphenols by electrochemical oxidation when the effect of variation of operating parameters on the process efficiency was assessed. In addition, the project concluded with a technology for treating industrial effluents from metal machining processes and textile facilities by electrochemical oxidation of ethoxylated nonyl-phenols at DSA.
