In this project, the removal of Acid Red 114(AR 114) that is a mono Azoo dye with global usage in aqueous environment was explored by nano photo catalytic process. The ZnO was supported on Bentonite and used at suspension state in a batch photo reactor. The catalyst was synthesized by co precipitation methods and characterized by Scanning Electronic Microscopy (SEM), X-Ray Diffraction (XRD), and Fourier Transform Infrared (FT-IR) spectra. The effect of operational variables including pH, initial concentration of Acid red 114, amounts of catalysts and temperature were investigated on the removal efficiency of AR114. The optimum conditions were achieved at 1g/l of catalyst, 30 mg/l of AR 114, pH of 9 and temperature at 35℃. The removal of AR 114 in UV, UV/ZnO, and UV/ZnO/Bentonite process were 26.5, 55 and 92.5% after 2 h of treatment, respectively. The photo catalytic degradation mechanism was described and the efficiency of the process increased considerably by modification of photo catalyst. Manuscript profile
