Abstract
Abstract Carbofuran formulations are cleaned up by thin layer chromatography to separate possible interferences from carbofuran. Carbofuran phenol is reacted with vanillin to form a colored compound with an absorption maximum at 550 nm. The relationship between absorbance and concentration of carbofuran is linear from 5 to 50 μ5 ml solution. Recoveries of carbofuran from laboratory-prepared formulations ranged from 98.0 to 98.93%.
