有机磷农药光催化降解动力学的研究

Study on the Kinetics of Photocatalytic Degradation of Organophosphorous Pesticides

低浓度有机磷农药光催化降解符合一级动力学方程。本文根据Langmuir--Hinshelwood 方程,把气固催化反应动力学理论应用到液固催化反应,建立了有机磷农药光催化降解的动力学模型,验证了实验结果。

The rates of photocatalytic degradation of organophosphorous pesticides follow the first or- der reaction kinetics.In thispaper,according to Langmuir-Hinshelwood equation,put the theory of gas-solid catalytic reaction kinetics directly applied to the liquid-solid catalytic re. ction,kineties model of photocatalytic degradation of organophosphorous pesticides were es- tablished.The experimental result was confirmed.
