HIGH PERFORMANCE LIQUID CHROMATOGRAPHIC GRADIENT ELUTION FOR SIMULTANEOUS ANALYSIS OF TWENTY EIGHT ORGANOPHOSPHORUS AND ORGANOCHLORINE PESTICIDES

摘要

This invention describes a methodology for quantitative determination of 28 pesticides which include 18 organophosphorus i.e., acephate, chlorpyriphos, chlorpyrifphos- methyl, diazinon, diclorvos, dicrotophos, dimethoate, fenitrothion, malaoxon, malathion, monocrotophos, paraoxon-ethlyl, parathion-methlyl, phorate, phosphamidon, profenophos, quinalphos, and tetrachlorvinphos, and 10 organochlorine i.e., aldrin, diendrin, endosulfan- endrin, heptachlor, lindane, 2-4’ DDE, 2-4’ DDT, 4-4’ and DDT by binary gradient elution on HPLC system with dimethyloctadecylsilyl bonded silica Column (C18, 300 mm length, 3.9mm
