A preconcentration-separation procedure has been established based on solid-phase extraction of Fe(III) and Pb(II) on bucky tubes (BTs) disc. Fe(III) and Pb(II) ions were quantitatively recovered at pH 6. The influences of the analytical parameters like sample volume, flow rates on the recoveries of analytes on BT disc were investigated. The effects of co-existing ions on the recoveries were also studied. The detection limits for iron and lead were found 1.6 and 4.9 μg L⁻¹, respectively. The validation of the presented method was checked by the analysis of TMDA-51.3 fortified water certified reference material. The presented procedure was successfully applied to the separation-preconcentration and determination of iron and lead content of some natural water and herbal plant samples from Kayseri, Turkey.

“…The pH of the sample solutions plays a critical role on quantitative adsorption and recovery of trace elements on hydrophobic absorbents [31][32][33][34]. The effect of pH on the sorption efficiency of understudy metals ion in test solution was investigated by passing sample solution with pH in the range of 3-7 through the column at optimum value, and respective results are presented in Fig.…”

In this study, a solid-phase extraction method combined with atomic absorption spectrometry for extraction, preconcentration, and determination of iron (Fe(3+)), copper (Cu(2+)), and lead (Pb(2+)) ions at trace levels in water samples has been reported. The influences of effective parameters such as flow rate, pH, eluent conditions (type, volume, and concentration), sample volumes, and interference of matrix ions on metal ions recoveries were studied. Under optimized conditions, the limits of detection were found in the range of 0.7-2.2 μg L(-1), while preconcentration factors for Fe(3+), Cu(2+), and Pb(2+) ions were found to be 166, 200, and 250, respectively, and loading half time (t (1/2)) values were less than 2 min for all analyte ions. The proposed procedure was applied for the determination of metal ions in different water samples with recovery of >94.4% and relative standard deviation less than 4.4% for N = 5.

“…However, the aforementioned methods, except for flame atomic absorption spectrometry (FAAS), involve significant cost and increased instrumentation complexity, which limits their widespread application in routine analytical work. FAAS is still being used because it combines fast analysis time, relative simplicity, and less cost (Mohammadi et al 2010). These methods have been routinely used to eliminate matrix effects and cope with low metal levels .…”

A new method for the determination of Cu(II) and Pb(II) by flame atomic absorption spectrometry (FAAS) after preconcentrating on a column containing Anoxybacillus sp. SO B1-immobilized Amberlite XAD-16 was developed. The functional groups of Anoxybacillus sp. SO B1 immobilized on Amberlite XAD-16 were characterized in KBr tablets by Fourier transform infrared (FT-IR) spectrometry. Various parameters such as pH, amount of the adsorbent, eluent type and volume, and flow rate of the sample solution were studied. The optimum pH values of quantitative sorption for Cu(II) and Pb(II) were found to be pH 7.0 and 5.0 and Cu(II) and Pb(II) ions could be quantitatively eluted with 5.0 ml of 1.0 mol L ¡1 HCI and 10.0 ml of 0.25 mol L ¡1 HNO 3 , respectively. Recoveries of Cu(II) and Pb(II) were found to be 100.9 § 1.57% and 100.3 § 0.49% (N D 5), the limits of detection of Cu(II) and Pb(II) in the determination by FAAS (3 s, N D 10) were found to be 0.8 and 1.6 mg L ¡1 , respectively. The proposed enrichment method was applied for metal ion determination from water samples such as two parts of Tigris River water in Diyarbakır and Elazı g, Lake of Hazar in Elazı g, and tap water in Diyarbakır. Furthermore, the accuracy of the proposed method was verified by studying the analytical recovery and by analyzing certified reference material (NCS-DC 73350 leaves of poplar).
