| Abstract: | A spectrophotometric method for the determination of monuron and fenuron,two phenylurea herbicides, was described here. It was based on acidic hydrolysis of the herbicide, then followed by diazotization and coupling with chromotropic acid in alkaline medium. The absorption maxima of the coloured compound formed was measured at 515 nm and 510 nm respectively. The average recovery ratio was 85 %. The method was simple, convenient, rapid and economical. |
