Silica gel was functionalized with N-(2-aminoethyl)-2,3-dihydroxybenzaldimine group (AEDHB-SG) andcharacterized by elemental analysis and FT-IR spectroscopy. Preconcentration conditions of Cd(II), Cu(II),Ni(II) and Pb(II) were investigated on the AEDHB-SG loaded column using a solid phase extractiontechnique. The effects of parameters such as the pH, sample volume, flow rates, matrix ions wereexamined. Adsorption capacity of AEDHB-SG for Cd(II), Cu(II), Ni(II) and Pb(II) was 0.40, 0.56, 0.50 and0.23 mmol g 1. The accuracy of the developed method was confirmed by certified reference materials. Optimized method was applied to water and food samples for the determination of trace metals usingICP-OES.
