There we will focus on the water pollution which is an important problem. This work aims to study the photocatalytic degradation of chlorophenols. They belong to a notable group of pollutants because of their high toxicity, and hardly biodegradable, and are difficult to remove from the environment. Photocatalytic degradation of chlorophenols using UV light was investigated over mesoporous catalysts. Ti-MCM-41(20), Ti-MCM-41(10), TiO2/MCM-41, Fe-Ti-MCM-41, TiO2/Fe-MCM-41 and TiO2/SBA-15 catalysts were prepared from the corresponding metal salts by the sol-gel technique. The catalyst were invest...

Ti-MCM-41(20), Ti-MCM-41(10), TiO2/MCM-41, Fe-Ti-MCM-41, TiO2/Fe-MCM-41 and TiO2/SBA-15 catalysts were prepared from the corresponding metal salts by the sol-gel technique. The catalyst were investigated using X-ray diffraction (XRD), FT-IR spectroscopes, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and BET surface areas of the samples were determined using the nitrogen adsorption and desorption isotherms. 100 ppm was used as model pollutants. High purity 2,4,6-trichlorophenol and 4-chlorophenol solutions individually and 0.1 g/L of each catalyst was tested at different irradiation times. At each interval time 10 ml of irradiated solution was taken and analyzed by High Performance Liquid Chromatography (HPLC), Ion Chromatography (IC). Aromatic interme
