چکیده انگلیسی
A solid phase extraction method was developed for the preconcentration and separation of trace amounts of chromium, manganese, iron, cobalt, copper, cadmium and lead from environmental samples by complexation with alpha-benzoin oxime followed by adsorption onto Diaion SP-850-solid phase extraction column. One molar per liter HNO3 was used as eluent. The recoveries of analytes at pH 8.0 with 700 mg of resin were greater than 95% without interference from alkaline, earth alkaline and some metal ions. The detection limits by three sigma for analyte ions were 0.65 μg lâ1 for Cr(III), 0.42 μg lâ1 for Mn(II), 0.28 μg lâ1 for Fe(III), 0.73 μg lâ1 for Co(II), 0.30 μg lâ1 for Cu(II), 0.47 μg lâ1 for Cd(II) and 0.50 μg lâ1 for Pb(II). The validation of the procedure was performed by the analysis of the certified standard reference materials. The presented procedure was applied to the determination of analytes in tap, river and sea waters, rice, wheat, canned tomato and coal samples with successfully results (recoveries greater than 95%, R.S.D.'s lower than 8%).
