PHOTO-CATALYST DEGRADATION OF TARTRAZINE COMPOUND IN WASTEWATER USING TiO2 AND UV LIGHT

Abstract

Organic contaminants present in industrial wastewater are of major concern with respect to the health of the general public. Photo-catalytic process, one of the Advanced Oxidation Processes, is a promising technology for remediation of organic pollutants at ambient conditions. Photo-catalytic processes in the presence of TiO2 provide an interesting method to destroy hazardous organic contaminants. The experimental results showed that considerable degradation of Tartrazine organic compound has been achieved by combination of TiO2 and UV light, the process followed first order kinetics. The results showed that the increased level of TiO2 concentration does not necessarily increase the rate of degradation of organic compounds. Also, it was found that the higher the TiO2 concentrations the higher the pH values and more oscillatory behaviors were observed. Not much effect has been noted on the process due to temperature variation.
