The photochemical degradation of Monosulfuron irradiated by high pressure mercurylamp (HPML), ultraviolet light and sunlight was investigated. The effects of different typesof water, dissolved oxygen on the photodegradation of Monosulfuron in aqueous solutionwere studied. By GC-MS, photoproducts of Monosulforn in acetonitrile was detected. Thepathway of Monosulfron photodegradation in acetonitrile under HPML was proposed..
1. The analytical method of monosulfuron by HPLC was established. A colum...
