ABSTRACT
A simple and rapid procedure was developed for the flow injection (FI) pectrophotometric determination of carbofuran in pesticides formulations. The determination was based on the alkaline hydrolysis, at room temperature, of the carbofuran to yield carbofuran-phenol which can be coupled with diazotized sulphanilic acid in order to achieve an appropriate selectivity and sensitivity. The calibration graph is linear over the range 0.5-60 mg/L of carbofuran. The method has provided a detection limit of 0.5 mg / L, and the precision was better than 0.6% (R.S.D.) at a throughput of 80 samples per hour.
