Supramolecular solvent based microextraction for the preconcentration of Pb2+ and Cd2+ prior to spectrophotometric detection
Abstract:Supramolecular solvent based dispersive liquid-liquid microextraction technique has been developed as a preconcentration tool for the determination of trace level of Pb 2+ and Cd 2+ . Dodecanol dispersed in tetrahydrofuran has been utilized as a supramolecular-solvent system for the extraction of analytes prior to their quantitative determination with graphite furnace atomic absorption spectrophotometer. Both Pb 2+ and Cd 2+ were complexed with dithizone followed by the addition of supramolecular solvent, whic… Show more
