Detoxification of water containing paramethyl thiophenol with photocatalytic oxygenation on titanuim dioxide

Abstract

The photoassisted oxidation of water containing paramethyl thiophenol (PMTP) was investigated, over a heterogeneous catalyst of TiO2 (anatase/rutile) in a photocatalytic reactor. The effect of some physical and chemical parameters such as irradiation time, amount of TiO2, flow of O2 and pH were studied in order to optimise the process. Carbon dioxide an d sulphate ion yield measurements indicte that almost complete minzeralization occurs in the final phase of oxidation.
