The photolytic kinetics of Anilide herbicides pretilachlor in aqueous solution irradiated by HPML, UV and sunlight was investigated. The following effects on photolysis of pretilachlor under HPML were also studied: temperature, water types, pH buffers, surfactants, nitrate and nitrite, dyes, metallic ions and fertilizers. At the same time, the effect mechanism of H2O2 on pretilachlor was roughly expounded with PNDA as a·OH probe. The main results were summarized as follows:
1. The direct photodegr...
