“…It was observed that the column could be reused up to 100 runs without a decrease in the recoveries of cadmium(II). The number of adsorption-desorption cycles of the proposed nanosorbent is significantly higher than the conventional sorbents previously reported in the literature [8,30].…”

“…Instead of the use of fresh solvent as an extracting phase for each sample, the reusability of adsorbent was as high as greater than 30 cycles without any loss in its sorption behavior. A comparison of the proposed method with the other reported preconcentration methods [31][32][33][34][35][36][37][38][39] for zinc and thallium extraction from water samples are given in Table 6. The obtained detection limits by the proposed method are comparable to most of those reported in the literature.…”

The potential of modified multiwallcd carbon nanotubes, as a solid-phase extraction sorbent for the simultaneous separation and preconcentration of zinc and thallium has been investigated. Zinc and thallium were adsorbed quantitatively onto modified multiwalled carbon nanotubes in the pH range of 3 -6.5. Parameters influencing the simultaneous preconcentration of Zn(II) and Tl(I) ions such as pH of the sample, sample and eluent flow rate, type and volume of elution solution and interfering ions, have been examined and optimized. Linearity was maintained between 0.1 to 20.0 µg·mL -1 for thallium and 20.0 ng·mL -1 to 5.0 µg·mL -1 for zinc in the final solution. The defection limits based on three times the standard deviation of the blank signal (n = 8) for thallium and zinc were 5.1 and 1.4 ng·mL -1 , respectively. Seven replicate determination of a mixture of 5.0 and 0.2 µg·mL -1 of thallium and zinc in the final solution gave a mean absorbance of 0.085 and 0.074 with relative standard deviation 1.5% and 1.7%, respectively. The method has been applied for the determination of trace amounts of zinc and thallium in biological and water sample with satisfactory results.

“…The theoretical preconcentration factor, calculated as the ratio of the initial sample volume (1000 mL) to the final volume after preconcentration (10.0 mL), was 100. According to the figures of merit of the proposed method in comparison with other reported solid phase extraction methods, 26,[37][38][39] the proposed method showed very good sensitivity and precision for determining Cu 2+ and Pb 2+ ions. The results are summarized in Table 1.…”

Recebido em 21/3/13; aceito em 16/5/13; publicado na web em 25/7/13 A simple and fast approach for solid phase extraction is herein described, and used to determine trace amounts of Pb 2+ and Cu 2+ metal ions. The solid phase support is sodium dodecyl sulfate (SDS)-coated γ-alumina modified with bis(2-hydroxy acetophenone)-1,6-hexanediimine (BHAH) ligand. The adsorbed ions were stripped from the solid phase by 6 mL of 4 M nitric acid as eluent. The eluting solution was analyzed by flame atomic absorption spectrometry (FAAS). The sorption recovery of metal ions was investigated with regard to the effects of pH, amount of ligand, γ-alumina and surfactant and the amount and type of eluent. Complexation of BHAH with Pb 2+ or Cu 2+ ions was examined via spectrophotometry using the HypSpec program. The detection limit for Cu 2+ was 7.9 µg L -1 with a relative standard deviation of 1.67%, while that for Pb 2+ was 6.4 µg L -1 with a relative standard deviation of 1.64%. A preconcentration factor of 100 was achieved for these ions. The method was successfully applied to determine analyte concentrations in samples of liver, parsley, cabbage, and water.
