“…[21] This technique suffers from some drawbacks such as chemical interference from the sample matrix and high detection limit. In order to overcome these problems, various preconcentration/separation methods including cloud point extraction (CPE), [22] solid-phase extraction (SPE), [23][24][25][26] solid phase microextraction (SPME) [27][28][29][30] and dispersive liquid-liquid microextraction (DLLME) [30][31][32][33][34] were used. Homogeneous liquid-liquid extraction (HLLE) method as a sample preparation technique utilizes phase separation phenomenon from a homogeneous solution, and target solutes are extracted into a separated phase.…”

A new aeration-assisted homogeneous liquid-liquid microextraction using high-density solvent for determination of copper, nickel and cobalt, as a prior step to their determination, coupled to flame atomic absorption spectrometry is presented. Under the optimum conditions, the calibration graphs were linear in the range of 5.0-600.0 ng/mL for copper, 10.0-450.0 ng/mL for nickel and 8.0-500.0 ng/mL for cobalt. The limits of detection were 1.3, 3.6 and 2.7 ng/mL and the enrichment factor estimated to be 350, 340 and 360, for copper, nickel and cobalt, respectively. The proposed method was successfully applied for the determination of these cations in different samples. ARTICLE HISTORY

The adsorption of metallic elements on the solid phase chelating resins is probably the most effective separation and preconcentration methods. In this work, portable Solid phase extraction (SPE) was constructed using a commercially available plastic syringe containing certain amount of the Analiq ME-02 chelating resin. The ability of this portable SPE was evaluated through adsorption-desorption process of copper, lead, and cadmium prior their determination by atomic absorption spectrometry (AAS). Some parameters affecting the adsorption-desorption of these heavy metal ions on the Analiq ME-02, which include effect of pH and concentration of eluent ((HNO 3 ), were investigated in detail. It was found that quantitative adsorptions (> 90%) of copper, lead, and cadmium are obtained at all pHs (4-8) examined, whereas 1 M HNO 3 was found to be effective for the desorption of these metals with the recoveries in the range of 93 -114%. Such results indicated that Analig ME-02 has excellent chelating ability (pH-independent) for the adsorption of copper, lead, and cadmium, while portable SPE system provides easiness and effectiveness for collection/preconcentation of metallic elements.

“…For this reason, it is an important necessity to subject samples to a separation/preconcentration procedure before determining trace metals. 6,7 There are many methods for separation and preconcentration, such as ion-exchange, 8 liquid-liquid extraction, 9 coprecipitation 10,11 and solid-phase extraction. 12,13 Among these, solid phase extraction is commonly used, and is a very favorable technique.…”

A new chelating resin was synthesized by immobilizing 1-(2-thiazolylazo)-2-naphthol through the -N=N-group on Amberlite XAD-1180. The resin was used for the preconcentration of Cd(II), Co(II), Cu(II), Mn(II), Ni(II), and Pb(II) ions and their determination by flame atomic absorption spectrometry (FAAS). The influences of some analytical parameters, such as the pH, volume of the sample, flow rates of the sample and eluent, matrix components, amount of the resin, and amount and type of the eluent on the recovery, were investigated. Those metals retained on the resin at pH 8.5 were eluted with 25 mL of 2 mol L -1 HNO3. The sorption capacity of the resin was determined, except for Pb(II). The recoveries were found to be ≥95%, and the relative standard-deviation values were ≤4.3%. The detection limits were in the range of 0.1 -3.6 μg L -1. For the accuracy of the method, the analysis of a certified reference material was performed. This method was applied to environmental water samples.
