Abstract
Acid Red 206 (C40H20CaN4O8S2) is a textile dye with global usage which is found in sewage of textile manufacturing industries in large quantity. In this research the reaction of Acid Red 206 (AR206) in photocatalytic analysis was carried out in water with use of Taguchi method, Qualitek-4 software and catalyst suspension ZnFe2O4/Clinoptilolite and UV light radiation. To identify prepared catalyst, SEM image and XRD diffraction pattern were used. Based on Taguchi method the test results displayed the maximum photo catalytic activity. From kinetic view the reaction was first order and study of reaction rate was carried out with the use of first order kinetic equation and acceptable results were gained in this consideration. The effect of factors in photo catalytic analysis such as pH, the amount of hydrogen peroxide , photo catalyst and temperature of reaction, were examined and the most efficiency in optimum conditions ( pH=5, hydrogen peroxide=1ml, nonophotocatalyst=75 ppm and temperature=20ºC) was observed. According to these results, a method was obtained for photo catalytic analysis with the use of ZnFe2O4/ Clinoptilolite catalyst and UV light radiation, which by its development in an industrial form; it can be used for analyzing the wastewater in loom or other industries.
