| Abstract: | With rhodamine B as the target compound,the kinetics model for TiO2-photocatalyzed degradation was inversitigated in suspending system with KL-1 model photochemistry reaction instrument.The main parameters involved in the model are initial concentration of rhodamine B,TiO2 dosage,pH and physical properties of the reactant(such as molar volume and aqueous solubility).The results showed that the reaction rate is linear to the initial concentration.But the relationships between the reaction rate and TiO2 dosag... |
