Abstract:
A spectrophotometric method for the assay of Isoproturon and Metoxuron in technical grade and formulation samples has been developed using the oxidative coupling reaction with 3-methylbenzothiozolin-2-one hydrazone hydrochloride (MBTH). The reaction variables have been optimized and the reaction mechanism is discussed. The method is simple, rapid and has been successfully applied for the assay of Isoproturon and Metoxuron in commercial grade technical and formulated samples. The percent relative standard deviation is found to be in the range 0.34-1.00 for Isoproturon and 0.33-0.57 for Metoxuron.
