Removal of Phenolic Compound by Advanced Oxidation Processes (Fenton Process): A Review Paper

Abstract

The simultaneous occurrence of Fenton and photo-Fenton reactions is an attractive process for contamination remediation involving high toxicity and low biodegradability species. A multivariate experimental design can be applied to the treatment of industrial influent containing Phenolic compound in order to evaluate the use of the Fenton reagent under light irradiation (wavelength close to 400 nm for Photo-Fenton Reactions and up to 550 nm for Fenton-like reactions). Hence, this paper gives evolution of toxicity through all the degradation process by characterizing the toxicity level of phenolic compound and its reaction intermediates as a function of temperature and the Fenton reagent loads. Hydrogen peroxide concentration appears as a main direct effect for a favorable TOC reduction. Temperature has also an important effect in the phenolic compound degradation.
