In order to optimize the purification of water and sewage water, a new technique of degradation «the heterogeneous photocatalysis» of the organic matter was underlined. As catalyst we chose a semiconductor which is dioxide TiO2 the titanium in the presence of a lamp UV as source of energy. One model substances present in many industrial effluents: the 4-iso propyl phenol was selected. The results of our experiments show that the adsorption of the pollutant (10-4mol/l) on TiO2 supported in absence of radiation UV is negligible. Compared to direct photolysis UV (365 nm), the devolution of the pollutant is definitely faster in the presence of TiO2/UV for the same experimental conditions.
