In this study the Cloud Point Extraction has been used as a separation technique that uses a surfactant instead of organic solvents for phase separation. CPE has been alsoutilized as a pre-concentration strategy prior to the determination of trace levels of Copper and Nickel ions in water by flame atomic absorption spectrometry (FAAS). Di benzyl dithiocarbamate have beenprepared from amines in the presence of sodium salts and carbon disulfide. The prepared compounds were characterized by means of Elemental Analysis, IR, 1H NMR, Mass, and CHN spectroscopy. Application of the Cloud Point Extraction formation of the complexes dithiocarbamate with Copper and Nickel has been investigated, which was characterized by (UV-Vis), where it has been shown a stoichiometry of the complex. When Its ratio was 1:2, the results were identical to what is expected scientifically after studying the optimal experimental conditions. Then, the optimal conditions for the Cloud Point Extraction such as pH of the aqueous solution, concentration of the DDTC, amount of the surfactant, incubation temperature and time was covered. Under the optimal experimental conditions with a limit of detection, LOD at 0.012μg/ml, limit of quantization, LOQ, of 0.04μg/ml, and sensitivity of 5*10 −3 . The developed method was successfully applied for the determination of trace levels of lead ion in samples electrical power plant water.
