Simultaneous determination of clofentezine fenoxycarb and hexythiazox by hplc on apples pears and their pulps


, : Simultaneous determination of clofentezine fenoxycarb and hexythiazox by hplc on apples pears and their pulps. Pesticide Science 30(1): 13-20

The simultaneous HPLC determination of clofentezine, fenoxycarb and hexythiazox in apples, pears and their pulps is described. The method is based on a clean-up procedure carried out on a SepPak C18 cartridge followed by HPLC analysis on an RP-18 column using acetonitrile + water as mobile phase. Average recoveries were 85.0% for clofentezine, 84.8% for fenoxycarb and 75.6% for hexythiazox on apple matrix; recoveries from pear matrix were in the same range. UV detection limits at 240 nm were 0.07 mg kg-1 for clofentezine, 0.064 mg kg-1 for fenoxycarb and 0.08 mg kg-1 for hexythiazox.
