Double-phase liquid membrane extraction for the analysis of pesticides
A simple and solvent minimized sample preparation technique based on two-phase hollow fiber-protected liquid-phase microextraction was investigated for HPLC analysis of selected pesticides in water samples. Four pesticides (procymidon, methidation, quinalphos, and vinclozolin) were considered a...

| description | A simple and solvent minimized sample preparation technique based on two-phase hollow fiber-protected liquid-phase
microextraction was investigated for HPLC analysis of selected pesticides in water samples. Four pesticides (procymidon,
methidation, quinalphos, and vinclozolin) were considered as target analytes. Parameters such as extraction solvent, salt
concentration, stirring speed, extraction time, and pH value were optimized using spiked deionised water samples. The
analytes were extracted from 12 mL water samples through organic solvent (n-hexane and isooctane) immobilized in the
pores of a porous polypropylene hollow fiber into 50 µL acceptor phase present inside the hollow fiber. Excellent
separations of analytes were obtained on C18 column using acetonitrile-water ratio of 55:45 v/v at elevated flow rate of 0.8 mL/min. |
