“…Stretching vibrations of C-N group slightly shift (≈10 cm -1 ) toward the high field (structure A). The obtained spectral data are in agreement with the results of other researchers [14,25,26] and confirm the structure of complex compounds of the general formula [Cu(HL)Cl 2 ] 2 obtained via direct and counter synthesis.…”

“…This method has a very low limit of detection (LOQ), good relative standard deviation (RSD) and was applied to determine trace amounts of Zn 2+ and Cd 2+ ions in various real samples. In a full comparison of the results presented in this paper with those using similar methods reported in literature 1,7,8,13,43,44 (Table 6) revealed that, on key measurements, the proposed method proved comparable or superior to the reported methods.…”

Recebido em 27/3/12; aceito em 20/10/12; publicado na web em 21/2/13 A simple, sensitive and selective cloud point extraction procedure is described for the preconcentration and atomic absorption spectrometric determination of Zn 2+ and Cd 2+ ions in water and biological samples, after complexation with 3,3',3",3'"-tetraindolyl (terephthaloyl) dimethane (TTDM) in basic medium, using Triton X-114 as nonionic surfactant. Detection limits of 3.0 and 2.0 μg L -1 and quantification limits 10.0 and 7.0 μg L -1were obtained for Zn 2+ and Cd 2+ ions, respectively. Relative standard deviation was 2.9 and 3.3, and enrichment factors 23.9 and 25.6, for Zn 2+ and Cd 2+ ions, respectively. The method enabled determination of low levels of Zn 2+ and Cd 2+ ions in urine, blood serum and water samples.

“…In view of the high selectivity provided by flame atomic absorption spectrometry, the only interferences studied were those related to the preconcentration step. Cations that may react with IDPI, and anions that may form complexes with the metal ions were studied [43][44][45][46]. The results were shown in Table 4.…”

A simple, sensitive and feasible cloud-point extraction (CPE) methodology has been developed for the separation and preconcentration of cadmium and lead ions in real samples. The metals in the aqueous solution were complexes with 2-(3-indolyl)-4,5 di phynyl imidazole.(IDPI), at pH = 7.0 and Triton X-114 was added as surfactant. The variables effecting like concentration of Triton X-114 and HNO3, bath temperature, centrifuge rate and time on the cloud-point extraction were optimized. Under optimum conditions, the response are linear over concentration range of 0.025-1.3(µg mL-1) for Cd 2+ , 0.064-1.27(µg mL-1) for Pb 2+ andRSD % (n =5) 1.4 for Cd 2+ , 1.3 for Pb 2+ , detection limits (3SDb/m, n =10, m = slope of calibration) of 0.15 (µg.mL-1) for Cd 2+ and 0.13 (µg.mL-1) Pb 2+ respectively. The enrichment factors were 31 for Cd 2+ and 37 for Pb 2+. The preconcentration factors were 26 for Cd 2+ and 31 for Pb 2+ respectively.
