Investigation of photodegradation and hydrolysis of selected substituted urea and organophosphate pesticides in water

Introduction  

Photodegradation and hydrolysis of two substituted urea herbicides, monolinuron 3-(4-chlorophenyl)-1-methoxy-1-methylurea] and linuron 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea], and one organophosphorous insecticide, phoxim 2-(diethoxyphosphinothioyloxyimino)-2-phenylacetonitrile], were studied using buffered sterilized distilled water (pH 4, 7 and 9).
