Abstract
The photocalytic degradation of Rhodamine B by nano TiO 2 was studied under irradiation of 4W UV lamp in Rhodamine B aqueous directly with different initial concentration of Rhodamine B and different amount of catalysis.The results of the experiments indicated that the reaction rate increases with the increase of the initial concentration of Rhodamine B,and the reaction rate increases with the increase of the amount of catalysis.The photocalytic degradation of Rhodamine B is a complex reaction.The total reaction is a first order kinetic model.
