“…A comparison of the proposed co-precipitation procedure in this study with the other reported preconcentration methods for cadmium, nickel, chromium, lead and cobalt ions extraction from water samples are shown in Table 4 (Bulut et al 2010;Feist and Mikula 2014;Soylak and Aydin 2011;Soylak et al 2007Soylak et al , 2008Tuzen and Soylak 2009). Using similar precipitate dissolving media (HNO 3 ), the coprecipitation procedure for metal ions with 8-hydoxyquinoline as a ligand yielded low precipitation factor (PF) compared to those reported in the literatures for which other ligands were used (Table 4).…”

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.

“…Coprecipitation is also one of the efficient separation/preconcentration techniques for traces of heavy metal ions (Bulut et al, 2010;Saracoglu et al, 2006;Tuzen and Soylak, 2009;Zhang et al, 2004). The coprecipitation technique has some advantages: simple, fast method and several analyte ions can be preconcentrated and separated from the matrix simultaneously.…”

“…In the coprecipitation procedure, a precipitate is formed by combination of a carrier element and a suitable inorganic or organic ligand (Divrikli and Elci, 2002). Various carrier elements including copper, nickel, aluminum, erbium, magnesium, indium, and samarium have been used (Bulut et al, 2010;Divrikli and Elci, 2002;Doner and Ege, 2005;Saracoglu et al, 2006;Soylak and Tuzen, 2008;Zhang et al, 2004;Uluozlu et al, 2009Uluozlu et al, , 2010.…”

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.

2-(3-indolyl) -4,5 di phynyl imidazole(IDPI), was used as a complexing agent in cloud point extraction for the first time and applied for selective pre-concentration of trace amounts of Aluminium. The method is based on the extraction of Aluminium at pH 3.5 by using nonionic surfactant T-X114 and 2-(3-indolyl) -4,5 di phenyl imidazole.(IDPI) as a chelating agent. The adopted concentrations for IDPI, Triton X-114 and HNO3, bath temperature, centrifuge rate and time were optimized. Linearity for Al was obeyed in the range of Al 3+ ion 0.2-20.0 ng mL -1 . The Detection Limit (n=10) 0.013(µg.mL -1 ) for Aluminium ion, and along with enrichment factor of 37 for Aluminium ion, RSD % (n=5) 1.3(µg.mL -1 ) for Aluminium ion was achieved. The high efficiency of cloud point extraction to carry out the determination of analytes in complex matrices was demonstrated. The proposed method was successfully applied to the ultra-trace determination of aluminium in real samples.
