摘要
We identified degradation products of chrolpyrifos with Cu2+ and Fe2+ in aqueous solutions. From all the data obtained, the results and the discussion could be summarized as follows: 1) Chlorpyrifos was hydrolysed to diethylphosphorothioate and 3,5,6-trichrolo-2-pyridinol by Cu2+. 2) Chrolpyrifos degradation by Fe2+ involved two different mechanisms. In the first step, chrolpyrifos was hydrolysed to diethylphosphorothioate and 3,5,6-trichrolo-2-pyridinol, and in the second step, 3,5,6-trichrolo-2-pyridinol was dechlorinated by Fe2+ to 2-pyridinol.
