The photochemical degradation of chlorotoluron irradiated by high pressure mercury lamp (HPML) was investigated. The effects of types of water, pH , pigments and surfactants on photodegradation of chlorotoluron in aqueous solution were observed. Photoproducts of chlorotoluron in aqueous solution under HPML were also identified. The main study results were summarized as follows:
1.The photodegradation half-life of chlorotoluron in aqueous solution under HPML and sunlight was 14.72 min and 192.54 h....
