Abstract

The widespread use of pesticides contributes to their existence in the environment. The compounds with photocatalytic activity in environmental matrixes play a significant effect on the photodegradation of pesticides. In order to clear the photolysis effects of the main characteristic inorganic metal elements in the of Panax ginseng field soil on fluazifop-p-butyl, a series of tests were carried out. The obtained results indicated that Mn2+ and Sn+ exhibited a significant photosensitization on the ultraviolet photodegradation of fluazifop-p-butyl. Also the high content of VO3- and Mo7O246- in the photolysis system showed a photoquenching on fluazifop-p-butyl, but the low content is a photosensitive effect. However, in the photolysis system, as the concentration of Co2+ and Li+ increases, the photoquenching effect on fluazifop-p-butyl becomes obvious, and no photosensitization at any tested concentration of them.
