“…Several methods for the determination of trace metals have been commonly conducted by flame atomic absorption spectrometry (FAAS) [22], graphite furnace atomic absorption spectrometry (GFAAS) [23], inductively coupled plasma-atomic/optical emission spectroscopy (ICP-AES/OES) [24][25][26] or inductively coupled plasmamass spectrometry.…”

The content of 21 elements in the peel of five apple cultivars was determined by using the inductively coupled plasma optical emission (ICP-OES) spectrometry. Among the major elements, the most abundant is K, followed by Ca, P, Na and Mg. The most abundant among the microelements are Fe, B, Mn, V, Cu and Zn. In terms of heavy metals (As, Cd, Pb), it can be concluded that the concentrations of As, Cd, Ni and Pb are below permissible levels prescribed by national legislation and EU Directives. The results obtained from this study show that there are no health risks from the consumption of apples when compared with the levels stipulated by health authorities. Principal component analysis (PCA) was applied to classify the analyzed elements in five apple cultivars according to their contents.

A razão entre o espectro contínuo e a transformada "wavelet" foi usada para a determinação simultânea de misturas ternárias de cobre, cobalto e níquel sem separação prévia. O método é baseado na reação de complexação destes cátions com 1-(2-piridilazo)-2-naftol (PAN) em meio micelar triton X-100, pH 8,0. Os resultados mostraram que Cu(II), Co(II) e Ni(II) foram determinados simultaneamente nos intervalos de concentração de 0,20-4,0, 0,20-4,0 e 0,50-7,0 mg L -1 , respectivamente. Foram selecionadas diferentes wavelets-mãe, da família das transformadas wavelet no contínuo, e aplicadas sob condições ótimas nas determinações multi-componentes. O método foi testado pela análise de várias misturas ternárias sintéticas de íons Cu(II), Co(II) e Ni(II). Usando as condições otimizadas, o método proposto foi aplicado com sucesso na determinação simultânea destes metais em algumas amostras reais incluindo comprimidos multivitamínicos, chá, cevada, espinafre, leite em pó, solo, água do mar e amostras de água de torneira.Ratio spectra-continuous wavelet transformation was used for the simultaneous determination of ternary mixtures of copper, cobalt and nickel without prior separation steps. The method is based on the complexation reaction of these cations with 1-(2-pyridylazo)-2-naphthol (PAN) in triton X-100 micellar media at pH 8.0. The results showed that Cu(II), Co(II) and Ni(II) could be determined simultaneously in the ranges 0.20-4.0, 0.20-4.0 and 0.50-7.0 mg L -1 , respectively. Different mother wavelets from the family of continuous wavelet transforms were selected and applied under the optimal conditions for multi-component determinations. The method was tested by analyzing various synthetic ternary mixtures of Cu(II), Co(II) and Ni(II) ions. Under the working conditions, the proposed method was successfully applied for the simultaneous determination of these metals content evaluation in some real samples including multivitamin tablet, tea, barley, spinach, chocolate, milk powder, soil, sea water and tap water samples.

“…Several materials have been proposed as a sorbent for the collection/concentration of trace elements using solid phase extraction technique, such as activated carbon [3][4][5], Amberlite XAD [6][7][8][9][10][11][12], Diaion [13], Chromosorb [14], silica [1], and alumina [15]. Activated carbon may provide economical advantage.…”

“…However, physical loading of a complexing agent on activated carbon suggested that such sorbent may have less durability due to the loss of complexing agent during sorption-desorption processes. The addition of a complexing agent to each sample prior to column treatment is considered to be disadvantageous due to high reagent consumption and more organic waste will be generated [3]. The utilization of p-dimethylamino-benzaldehyde-modified nanometer SiO2 prior to ICP-AES measurement allows simultaneous determination of trace amount of Cu(II) and Pb(II) [1]; the detection limit indicates that the sensitivity of this method is not sufficient to measure Cu(II) and Pb (II) in relatively clean environmental water.…”

A novel chelating resin functionalized with serine diacetic acid moiety was synthesized by using chitosan as base material, and applied to the collection/concentration of trace elements in environmental water samples, followed by the determination using inductively coupled plasma-atomic emission spectrometer (ICP-AES). The synthesized resin, crosslinked chitosan serine diacetic acid (CCTS-SDA), showed good adsorption behavior toward trace amounts of Cd, Pb, Cu, Ni, V, Ga, Sc, In, and Th in a wide pH range.Additionally, rare earth elements also can be retained on the resin at neutral pH region. The adsorbed elements can be easily eluted with 1 mol L -1 of nitric acid, and their recoveries were found to be 90-100%. The CCTS-SDA was packed in a mini-column, which was then installed in a computer-controlled auto-pretreatment system (Auto-Pret System) for on-linetrace elements collection and determination with ICP-AES. Experimental parameters which related to the improvement of sensitivity and reproducibility were optimized. The limit of detections (LOD) for 13 elements were found to be in sub-ppb level. The proposed method with CCTS-SDA resin was successfully applied to the determination of trace elements in river water samples. The method was validated by determining a certified reference material of river water, SLRS-4.
