Decomposition of 2-chlorophenol in aqueous solution by UV irradiation with the presence of titanium dioxide

摘要: Abstract The decomposition of 2-chlorophenol in aqueous solution by UV TiO 2 oxidation process was studied under various pH values, light intensities and types TiO2. removal organic intermediates found to be more effective for acidic solutions. can fitted well a pseudo first-order kinetics. Experimental results indicated that the distribution non-chlorinated chlorinated on photocatalytic rate were highly dependent pH. At same intensity, adequate dosage TiO2 less alkaline solutions than Increasing intensity would significantly increase at 3, but not 11. Both rutile anatase forms used this study. destruction unit weight anatase. However, rates surface area both almost research. Thus, difference might attributed TiO2, crystal properties.
