Photoassisted processes for the removal of organic pollutants in aqueous medium

Abstract

The core of this project consists in a bibliographic study (sections 3 to 10). Lately, the study of the removal of organic pollutants from aqueous medium has become an issue of growing concern, due to their negative environmental impact as a result of the high toxicity of most of the xenobiotics released into wastewater. Many organic compounds are very stable, resistant to common oxidants and non-biodegradable. Therefore, they cannot be eliminated by means of conventional water treatments. Some effective methods are: Fenton, photo-Fenton, photolysis or photoelectro-Fenton, among others. The project has been completed with a small experimental work (sections 11 and 12), aiming to put into practice the concepts investigated in the bibliographic part. This work is focused on the degradation of a dye, namely Indigo Carmine, from water by different photoassisted processes
