Abstract
Cloud point extraction (CPE), which is the most popular coacervate-based extraction method, was utilizedfor the separation and preconcentration of trace amounts of cadmium, lead, and nickel. Quinalizarin was used ascomplexing agent and Triton X-114 was used as surfactant. After extraction, analyte ions were determined by ameatomic absorption spectrometry. The detection limits (3s) of 1.8 g L1for Cd(II), 3.2 g L1for Pb(II), and 2.8 g L1for Ni(II) were obtained using 50 mL of solutions. The relative standard deviation was calculated as 4.3% for10 g L1Cd(II), 4.9% for 50 g L1Pb(II), and 4.6% for 50 g L1Ni(II). Obtained enrichment factors of Cd(II),Pb(II), and Ni(II) were 144, 129 and 92, respectively. In addition, the method was successfully implemented for thedetermination of Cd(II), Pb(II), and Ni(II) in water samples and standard reference materials and satisfactory recoveryvalues were obtained.
