In this study, Schiff bases of ONO type, tridentate, N-(2-hydroxyphenyl)-2-hydroxy-1-naphthaldymine and ONNO type, tetradentate, Bis-N,N’-(2-hydroxy-1 – naphthaldymine)-1,3-propandiamin were adsorbed on to silica gel to form two adsorbtion materials that used for solid phase extraction. These adsorption materials were investigated for enrichment of Cu2+ and Ni2+ ions. pH, eluent type, flow rate and the effects of foreign ions were examined for every ions. The concentrations of Ni2+ and Cu2+ ions were determined with flame atomic absorption spectroscopy. The study was carried out between pH 2 and 9 in order to select an optimum pH value. The regain value in the pre concentration process was observed to reach above 90% after pH value of 5 for ONNO type ligand. The regain value of ONO type ligand was below 90%. LOD and LOQ was calculated as 0,008 μg/mL and 0,024 μg/mL for Cu2+ respectively. Also LOD and LOQ was calculated as 0,016 μg/mL and 0,048 μg/mL for Ni2+. The accuracy of the method was tested by certificated reference standard materials, CRM BCR-397 human hair and NIST 2976 mussel tissue.
