| Abstract: | The paper is concentrated on the dynamics' study of LAS degradation by photocatalytic oxidation. Under constant STPP concentration, experiments in a certain range of temperature on LAS degradation with the change of ultraviolet light irradiating time are conducted. The reaction rate constant and the reactive order at different temperature, the reactive activation energy and the relationship between the reaction rate constant and temperature are obtained from the experiments. |
