Özet

A sensitive and simple method for the simultaneous preconcentration of Cr(3+), Fe(3+), Cu(2+), Ni(2+) Co(2+) and Zn(2+) in real samples has been reported. The method is based on the adsorption of analytes on his salicyl aldehyde, 1,3 propan diimine (BSPDI) loaded on activated carbon. The adsorbed metals on modified activated carbon were eluted using 8 mL of 2 mol L(-1) nitric acid in acetone or 10 mL of 4 mol L(-1) HNO(3). The influences of the analytical parameters including pH and sample volume were investigated. The effects of matrix ions on the retentions of the analytes were also examined. The recoveries of analytes were generally quantitative. The method has been successfully applied for these metals content evaluation in some food samples. (c) 2007 Elsevier B.V. All rights reserved.
