“…A comparison of the characteristic data of the presented methods with those reported in the literature is given in Table 4. It shows that the LOD and enrichment factor of our method are found to be comparable with previously reported methods, especially for the GF AAS technique [7,14,21]. In the case of [16,19,20] very low LODs, even several orders of magnitude lower than for some others, can result from the sensitivity of the ICP MS technique.…”

“…For this reason a separation/ preconcentration stage is often applied to remove matrix interferences and preconcentrate the analyte to a level at which it can be reliably determined. Various preconcentration approaches, such as: ion exchange [4,6,9,10,13], precipitation and coprecipitation [4,13], extraction techniques [4,[13][14][15][16][17][18][19][20][21][22] and biosorption [13,23] have been described in the literature for platinum separation from environmental samples. However, one of the most useful preconcentration treatments is adsorption onto solid adsorbents.…”

“…There is a growing interest in sorbents based on nanostructured materials such as magnetic nanoparticles (Zhou et al 2010;Li et al 2011a) and activated carbon materials (Tu et al 2011;Li et al 2011b). Ion imprinted polymers properties are remarkable because of their high selectivity towards the target ion due to a memory effect resulting from their preparation process (Godlewska-Żyłkiewicz et al 2010;Leśniewska et al 2011). …”

Metallic form of platinum is considered to be inert for biological reactions, but in contrast some Pt salts like hexachloroplatinate and tetrachloroplatinate, present at processes in platinum industry and at production of cytostatic platinum compounds, are among the most potent allergens and sensitizers. To assess their potential health risk, development of selective and sensitive analytical methods is inevitable. These compounds can be also found in various environmental compartments where they are released from car catalysts. However, the levels are often orders of magnitude lower which requires effective pretreatment prior to their analysis. In the present work, the most frequently methods used for the preconcentration as well as for speciation analysis of the chlorinated platinum compounds, either in occupational environment or in various natural matrices, will be presented and discussed.

“…Ion imprinted polymers (IIPs) show very interesting characteristics such as high selectivity, low cost, high surface area, durability and reusability. By reason of this, recently has been widely used for separation and preconcentration in solid phase extraction and electrochemical methods [21][22][23]. The application of modified carbon paste electrodes (MCPE) in Electrochemical methods has attracted considerable attention in recent years [16,24,25].…”

We have synthesized cadmium(II) ion-imprinted polymers (IIP) and non-imprinted polymers (NIP) using 1-(2-pyridylazo)-2-naphthol as a ligand. The materials were used to prepare a carbon paste electrode for the determination of Cd(II). Polymerization was performed with (a) methacrylic acid as a functional monomer, (b) ethyleneglycol dimethacrylate as the crosslinking monomer, and (c) 2,2′-azobis(isobutyronitrile) as the initiator. Imprinted cadmium ion was removed from the polymeric matrix using nitric acid. The measurements were carried out in an closed circuit after accumulation at −1.2 V, this followed by electrolysis of the accumulated Cd(II) by voltammetric scanning from −1.0 to −0.6 V. The parameters governing the response of the electrode were studied. Under optimized conditions, the response of the electrode is linear in the range from 2.0 to 200 ng mL −1 . The detection limit is 0.31 ng mL −1 . The relative standard deviations are ±3.4 and ±2.1 % for 7 successive determinations of 20.0 and 50.0 ng mL-1 of Cd(II), respectively. The method was applied to the determination of cadmium (II) in water and food samples.
