Abstract

The concentration of metal ions(Cd2+ Cu2+ Pb2+ Mn2+ Zn2+ and Fe3+) on 1-phenyl-3-methyl-4-stearoyl-5-pyrazolone (C18) loaded on silica gel(C18/SG) was investigated by batch and column methods. At pH values higher than 6, these metals were quantitatively retained on C18/SG. The adsorbent did not change its retention efficiency for the metals for at least 6 adsorption/elution cycles. Results of determinations of these metals in environmental samples were satisfactory.
