4DescriptionAbstract In this work, N(2-thiophenyl)-1-(2-hydoxyphenyl)Imine (NTPHPI) was used as a proper complexing agent for the preconcentration by cloud point extraction followed by atomic absorption spectrometric to determine of Ni2+, Cu2+ and Co2+ ions in real samples. NTPHPI and Triton X-114 were used as hydrophobic ligand and non-ionic surfactant respectively and the pH of 8 was chosen as optimum. Under the optimized experimental conditions, the selective preconcentration and determination of low concentration of Ni2+, Cu2+ and Co2+ ions as 1, 5 and 6 ng mL-1 can be made respectively. The proposed method was successfully applied to the preconcentration and low-level determination of the cited ions in different water, chocolate and honey samples.
