- Peroxicoagulation is an electrochemical advanced oxidation processes in which both ferrous ions and hydrogen peroxide are generated in the cell. Organic pollutants are thus removed by degradation and coagulation. The peroxicoagulation process is a combination of electro-Fenton and electrocoagulation processes. The peroxicoagulation process is very efficient for the removal of aniline and herbicides from water and for the treatment of landfill leachate and textile wastewaters. Under acidic conditions, electro-Fenton is the predominant removal means, whereas electrocoagulation is the main removal means under neutral and alkaline conditions. As a consequence, pH regulation to acidic conditions is essential for the mineralization of organic pollutants.
