خلاصه مقاله:

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.
