Photo-catalytic oxidation of 4-chlorophenol using TiO2-functionalized membranes

摘要

This work presents a hybrid method for advanced removal of 4-chlorophenol from water by combining the membrane and photo-catalytic processes. The hybrid method consists of photo-catalytic oxidation procedure using a photo-catalytic reactor equipped with a TiO2-functionalized membrane obtained by the sol-gel method. The photo-catalytic activity is dependent on the alcohol solvent type used for synthesis, which determines the TiO2 deposition and characteristics. At higher reaction time, the regenerated cellulose membrane becomes slightly unstable due to UV radiations and a strong oxidizing potential of the reaction medium.
