| Abstract: | With using Ti（OBu）4 as material,anhydrous ethanol as solvent,artificial zeolite（mesh for 40～60） as the carrier,the immobilized TiO2 photocatalyst was prepared by Sol-Gel technique.The photocatalytic oxidation experiment was implemented in a self-made reactor whose light resource is from the 40 W（253.7nm） ultraviolet radiation antiseptic lamp.The result indicates that the decoloration rate can reach over 80% when the initial concentration of the methylene blue is 15 ml/L,the heating temperature is 450 ℃,PH is about 2,the adding amount of catalyst is about 2.5 g/L and the reaction time is 2.5 h. |
