“…The analytical chemistry of the polymer PVP was studied by Tokman et.al, 2004 [14]. PVP forms complexes with metals via oxygen and nitrogen donor sites, due to the high polarity of the lactum ring conferred by resonance stabilisation facilitated by a near planer geometry.…”

“…The elemental determination by atomic absorption spectrometry [2,3] is frequently performed by line source spectrometers. Although the line-source flame atomic absorption spectrometry (LS FAAS) [4] is a worldwide, robust and well-established technique, the single-element analysis and narrow range calibration may be considered the main drawbacks of the technique when several elements are required: the changing and conditioning of hollow cathode lamps (or electrodeless discharge lamps) and the need for adjusting analyte absorbance within the linear working range of calibrating plots are time consuming and lead to increased analytical cost in large scale routine analyses [5].…”

This work describes a method to determine Cu at wide range concentrations in a single run without need of further dilutions employing high-resolution continuum source flame atomic absorption spectrometry. Different atomic lines for Cu at 324.754 nm, 327.396 nm, 222.570 nm, 249.215 nm and 224.426 nm were evaluated and main figures of merit established. Absorbance measurements at 324.754 nm, 249.215 nm and 224.426 nm allows the determination of Cu in the 0.07 – 5.0 mg L-1, 5.0 – 100 mg L-1 and 100 – 800 mg L-1 concentration intervals respectively with linear correlation coefficients better than 0.998. Limits of detection were 21 μg L-1, 310 μg L-1 and 1400 μg L-1 for 324.754 nm, 249.215 nm and 224.426 nm, respectively and relative standard deviations (n = 12) were £ 2.7%. The proposed method was applied to water samples spiked with Cu and the results were in agreement at a 95% of confidence level (paired t-test) with those obtained by line-source flame atomic absorption spectrometry.

“…The use of separation and preconcentration procedure for the determination of trace heavy metals prior to FAAS application is very important because analysis is achieved at lower level of detection limit than when the procedure in not applied. Also, the interference effects of the foreign ions in the samples are minimal when separation-preconcentration procedure is applied (Tokman et al 2004;Yang et al 2004). …”

Co-precipitation procedure has widely been employed for preconcentration and separation of metal ions from the matrices of environmental samples. This is simply due to its simplicity, low consumption of separating solvent and short duration for analysis. Various organic ligands have been used for this purpose. However, there is dearth of information on the application of 8-hydroxyquinoline (8-HQ) as ligand and Cu(II) as carrier element. The use of Cu(II) is desirable because there is no contamination and background adsorption interference. Therefore, the objective of this study was to use 8-HQ in the presence of Cu(II) for coprecipitation of Cd(II), Co(II), Cr(III), Ni(II) and Pb(II) from standard solutions and surface water prior to their determinations by flame atomic absorption spectrometry (FAAS). The effects of pH, sample volume, amount of 8-HQ and Cu(II) and interfering ions on the recoveries of metal ions from standard solutions were monitored using FAAS. The water samples were treated with 8-HQ under the optimum experimental conditions and metal concentrations were determined by FAAS. The metal concentrations in water samples not treated with 8-HQ were also determined. The optimum recovery values for metal ions were higher than 85.0%. The concentrations (mg/L) of Co(II), Ni(II), Cr(III), and Pb(II) in water samples treated with 8-HQ were 0.014 ± 0.002, 0.03 ± 0.01, 0.04 ± 0.02 and 0.05 ± 0.02, respectively. These concentrations and those obtained without coprecipitation technique were significantly different. Coprecipitation procedure using 8-HQ as ligand and Cu(II) as carrier element enhanced the preconcentration and separation of metal ions from the matrix of water sample.
