Abstract: 
A simple, sensitive and feasible cloud-point extraction (CPE) methodology has been developed for the separation and preconcentration of cadmium and lead ions in real samples. The metals in the aqueous solution were complexes with 2-(3-indolyl)-4, 5 di phynyl imidazole. (IDPI), at pH = 7. 0 and Triton X-114 was added as surfactant. The variables effecting like concentration of Triton X-114 and HNO3, bath temperature, centrifuge rate and time on the cloud-point extraction were optimized. Under optimum conditions, the response are linear over concentration range of 0. 077-1. 29 (μ g mL-1) for Zn2+ and RSD % (n =5) 1. 6 for Zn2+, Detection limits (3SDb/m, n = 10, m = slope of calibration) of 0. 14 (μ g. mL-1) Zn2+ respectively. The enrichment factors was 33, the preconcentration factors was 27 for Zn2+ respectively. The high efficiency of cloud point extraction to carry out the determination of analytes in complex matrices was demonstrated. The proposed method was successfully applied to the ultra-trace determination of cadmium in real samples.
