Abstract

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.
