Using Fe2O3 supported on Bentonite zeolite as a catalyst for photocalytic degradation of Azo dye pollutant (Acid red 206) in water

Organic dyes constitute one of the larger groups of pollutants in wastewater released from textile industries. Heterogeneous photo catalysis has been considered as a cost effective alternative for the purification of dye containing wastewater. Then the photo catalytic decomposition of organic compounds in wastewater has attracted a great deal of attention .A method of supporting Fe2O3 on zeolite , without losing the photosensitization of Fe2O3 and the adsorption properties of zeolite ,is the important aspect while preparing zeolite-Based photo catalysts. Results show that Fe2O3/Bentonite is an active photo catalyst for photo degradation of AR 206 pollutant in water. Based on these results ,a model highlighting the photo gradation activity of immobilized [Fe2O3/Bentonite] which may lead to the development of an easy and effective technology in wastewater treatments, is proposed.
