“…6 Thus, there is a great interest concerning the implementation of a reliable preconcentration system for lead(II) for analytical determinations. 7 Several methods extensively used for preconcentration include liquid-liquid extraction, [8][9][10][11] co-precipitation, 12-14 ion exchange, solid-phase extraction [15][16][17][18][19][20] and chelating matrices. To solve the problem of main problem of FAAS and ICP-AES techniques for trace analysis, solid-phase extraction is the one of the important preconcentration method.…”

A sensitive and simple solid-phase preconcentration procedure for the determination of trace amount of lead by flame atomic absorption spectrometry (FAAS) is developed. The method is based on the adsorption of Pb 2+ on the column of fine grinded eucalyptus stem adsorbent, elution of the column by nitric acid and subsequent determination by FAAS. The effect of different variables such as pH, eluent type, flow rate and interfering ions on the recovery of the analyte was investigated and optimum conditions were established. The adsorption of lead onto fine grinded eucalyptus stem can formally be described by a Langmuir equation with a maximum adsorption capacity of 4.49 mg g -1 . A preconcentration factor of 50 was achieved using the optimum conditions. The calibration graph was linear in the range 10-125 ng mL -1 of lead in the initial solution with r = 0.9982. The limit of detection based on 3S b criterion was 4.5 ng mL -1 and the relative standard deviation for eight replicate measurements of 30 and 80 ng mL -1 of iron was 3.6 and 2.8%, respectively. The method was successfully applied to the determination of lead added to well, tap and wastewater samples.

“…Some metals such as manganese and copper are essential micronutrients and have a variety of biochemical functions in all living organisms. While these elements are essential, they can be toxic when taken in excess (Ensafi and Shiraz, 2008;Hedberg et al, 2011;Mohammadi et al, 2013a). However, some metals such as cadmium are non-essential metals as they are toxic, even in traces (Ensafi and Shiraz, 2008;Hajiaghababaei et al, 2013;Hedberg et al, 2011).…”

A separation-preconcentration procedure was developed for the determination of trace amounts of copper, nickel, manganese and cadmium ions in water samples by flame atomic absorption spectrometry after coprecipitation by Co(OH) 2 as a carrier without a chelating agent. The influence of the various analytical parameters such as pH, amount of carrier reagent, standing time, centrifugation rate and time, sample volume and matrix effects on the recovery of the analyte ions was studied. Under the specified experimental conditions the calibration curves for Ni(II) and Cu(II) were linear from 0.5 to 200 ng mL À1 and for Mn(II) and Cd(II) from 0.5 to 250 and 0.3 to 80 ng mL À1 , respectively. The relative standard deviations for seven replicate determinations of a mixture of 40.0 ng mL À1 of Cu(II), Ni(II), Mn(II) and 20 ng mL À1 of Cd(II) in the original solution were 1.9%, 1.7%, 1.8% and 2.1%, respectively. The detection limits based on 3S b /m for Cu(II), Ni(II), Mn(II) and Cd(II) in the original solution were 0.2, 0.2, 0.3 and 0.07 ng mL À1 , respectively. The limits of quantification based on 10S b /m for Cu(II), Ni(II), Mn(II) and Cd(II) in the original solution were 6.7, 6.7, 10.0 and 2.3 ng mL À1 , respectively. The proposed method has been applied to the determination of trace amounts of the analyte ions in two certified reference materials (the National Institute for Environment Studies (NIES) No. 1 Pepperbush and NIES No. 7 Tea Leaves) and water samples and satisfactory results were obtained. ª 2014 The Authors.
