Electrochemical oxidation of organic pollutants for wastewater treatment

Abstract

This review supplies a current opinion about the most recent works, which have been carried out toward the electrochemical oxidation (EO) of organic pollutants for water treatment. In particular, the first section is focused on the direct EO or anodic oxidation, and the indirect EO by electrogenerated active chlorine, the most important mediated process. Meanwhile, the second section describes the use of promising cathodic processes as well as the recent progress of emerging photoassisted electrochemical treatments such as photoelectro-Fenton and solar electro-Fenton. The outlooks of these emerging processes for the upcoming future finally conclude this mini-review.
