Özet:

 

In the current study, a simple and efficient analytical method for   preconcentration and determination of Cd(II), Pb(II), and Sn(II) in some   cosmetic samples, using ultrasonic assisted-cloud point extraction and flame   atomic absorption spectrometry, was developed. The method is based on the   ternary complex formations of Sn(II), Pb(II), and Cd(II), which are   available in the form of neutral and/or anionic hydroxo complexes   (Sn(OH)−33−_{3}^{-}, Pb(OH)−33−_{3}^{-}, Cd(OH)22_{2}, and/or   Cd(OH)−3)3−)_{3}^{-}), with Victoria Pure Blue BO (VPB+)+)^{+}) in the presence   of cetylpyridinium chloride at pH 8.5, and then extraction of the formed   ternary complexes into the micellar phase of polyoxyethylene sorbitan   monostearate (Tween 60). Using the optimized conditions, a linear   relationship was observed in the ranges of 12-330 μμ\mu g L−1−1^{-1} for   Cd(II), 4-200 μμ\mu g L−1−1^{-1} for Pb(II), and 1-275 μμ\mu g L−1−1^{-1} for   Sn(II). The detection limits for Cd(II), Pb(II), and Sn(II), respectively,   were 3.70, 1.35, and 0.45 μμ\mu g L−1−1^{-1}, with a preconcentration factor   of 50, and the precision as relative standard deviations was lower than   4.2% for each analyte. The validity was verified by analysis of two   certified reference materials. Finally, the method was successfully applied   to the determination of these metals in various cosmetic samples.
