Özet

In this study, a simple and rapid solid phase extraction/preconcentration procedure was developed for determination of Cd(II), Co(II), Cr(III), Cu(II), Fe(III), Mn(II), Pb(II), and Zn(II) trace metals by flame atomic absorption spectrometry (FAAS). A new chelating resin, poly(N-cyclohexylacrylamide-co-divinylben zene-co-2-acrylamido-2-methyl-1-propanesulfonic acid) (NCA-co-DVB-co-AMPS) (hereafter CDAP) was synthesized and characterized. The influences of the analytical parameters such as pH of the sample solution, type and concentration of eluent, flow rates of the sample and eluent, volume of the sample and eluent, amount of chelating resin, and interference of ions were examined. The limit of detection (LOD) of analytes were found (3 s) to be in the range of 0.65-1.90 mu g L (1). Preconcentration factor (PF) of 200 and the relative standard deviation (RSD) of 62% were achieved (n = 11). The developed method was applied for determination of analytes in some dairy samples and certified reference materials. (C) 2016 Elsevier Ltd. All rights reserved.
