摘　　要：本文重点对光催化氧化法降解LAS的动力学进行了研究。STPP存在的条件下 ,在一定温度范围内 ,做了LAS随光照时间变化的降解实验。实验数据经分析处理得到各温度下的速率常数和反应级数、反应活化能 。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.
