A cloud point extraction procedure for the preconcentration of copper, nickel, iron and zinc ions in various samples has been described. Analyte ions in aqueous phase are complexed with 3-((indolin-3-yl)(phenyl)methyl)indoline (IYPMI) and following centrifugation quantitatively extracted to the aqueous phase rich in Triton X-114. The surfactant-rich phase was dissolved in 2.0 mol L−1 HNO3 in methanol prior to metal content determination by flame atomic absorption spectrometry (FAAS). The effects of some parameters including, the concentrations of IYPMI, Triton X-114 and HNO3, bath temperature, centrifuge rate and time were investigated on the recoveries of analyte ions. At optimum conditions, the detection limits of (3 SDb m−1) of 1.6, 2.8, 2.1 and 1.1 ng mL−1 for Cu2+, Fe3+, Ni2+ and Zn2+ along with preconcentration factors of 30 and enrichment factor of 48, 39, 34 and 52 for Cu2+, Ni2+, Fe3+ and Zn2+ respectively, were obtained. The proposed cloud point extraction has been successfully applied for the determination of metal ions in real samples with complicated matrix such as biological, soil and blood samples with high efficiency.

A method of separation and preconcentration for the determination of Zn, Cu, and Mn in natural water was described and real samples studied using flame atomic absorption spectrometry. The method is based on the adsorption of Mn 2+ , Cu 2+ and Zn 2+ onto 3-((1H-Indol-3-yl)(3-nitrophenol)methyl)-1H indole (INMI) that is loaded onto Triton X-100-coated polyvinyl chloride. The effects of pH, reagent amount, sample volume and matrix of the sample on the sorption of metal ions were also investigated. Detection limits (3 SDb/m) of 1.9, 2.1 and 1.8 ng mL −1 for Cu 2+ , Zn 2+ and Mn 2+ along with a preconcentration factor of 270 for these ions were achieved. We demonstrated highly efficient solid phase extraction for the determination of analytes in complex matrices. The proposed procedure was applied to analyses of industrial, natural and waste water as well as to those of soil and fruit samples.
