研究了照射光源、催化剂种类对水中有机磷农药(马拉硫磷)分解速度的影响。结果表明,远紫外光能够光分解马拉硫磷,若用波长大于360nm的光作为动力,在有TiO_2和氧存在的条件下,马拉硫磷可以发生光催化分解反应;在适当条件之下,太阳光也可以分解水中的马拉硫磷。
The effects of light source and catalyst type on the decomposition rate of organophosphorus pesticide (malathion) in water were studied. The results show that far ultraviolet light can decompose malathion. If light with a wavelength greater than 360 nm is used as a driving force, malathion can undergo photocatalytic decomposition reaction under the presence of TiO 2 and oxygen. Under the appropriate conditions The sun can also break down malathion in the water.
