Spectrophotometric determination of carbosulfan in environmental samples

This study presents carbosulfan determination by a novel rapid, simple, sensitive and an extractive method, which is based on alkaline hydrolysis of carbosulfan into phenol followed by Coupling with diazotized p-amino acetophenone in alkaline medium. Red brown dye (lambda(max) 465 nm) can be extractable in 2-methyl butanol, which makes reaction more sensitive with same lambda(max). Beer's law is obeyed between 0.8-5.6 ppm and 0.1-0.6 ppm in aqueous and extractive system respectively. Molar absorptivity and Sandell's sensitivity were found to be 4.46x 10(4) 1 mol(-1) cm(-1) and 0.0085 mu g cm(-2) respectively. Method has been satisfactorily applied for carbosulfan determination in various environmental samples.
