Abstract

A simple, sensitive, rapid , and versatile cloud-point extraction (CPE) methodology hasbeen improved for the preconcentration and determination nickel and cadmium ions. Theproposed method based on forming complexes with newly synthesized 6-(2-nitrophenylazo)-2-methyl-8-hydroxyquinoline[6-(2NPAM8HQ)]aschelatingagenttoformhydrophobic complexes and Triton X-114 was selected as surfactant. The analyte wasquantitatively extracted into the surfactant - rich phase and subsequently separated fromthe bulk aqueous phase by centrifugation and dilutedwith Ethanol and determined byUV/Visible spectrophotometry. The variables affecting the cloud point extraction such aspH, reagent concentration, surfactant concentration, equilibrium temperature, and timewere optimized. The detection limit is 0.062 μg ml−1 for nickel, and 0.047 μg ml-1forcadmium; the relative standard deviation for six replicate measurement is 0.84% , 1.04 %for nickel and cadmium respectively. The proposed method was successfully applied todeterminationofnickelandcadmium ionsinRicesamplesavailable inIraqimarket.
