Efficient Method Cloud Point Extraction for Separation Preconcentration and Trace amount Determination of Bismuth (III) from Different Samples by New Laboratory Prepared Azo Derivative

Abstract

By cloud point extraction methodology extracted Bi (III) after produced ion association complex with new laboratory prepared azo derivative AMIBSHA,in presence non-ionic surfactant Tritonx-100, the experiments show complex formation performed at pH=9 and heating for 20 minute at 90°C, the research involved determination all optimum values effect on the extraction efficiency, in addition to thermodynamic study and stoichiometry as well as interferences studies and electrolyte effect. With spectrophotometric determination in different samples. With detection limit =(7.764×10^-7µg.mL^-1) and Sandell’s sensitivity (9.749×10^-10µg.cm^-2) and ? = 21480.8 L.mol^-1.cm^-1and RSD% =0.00541.
