Özet

Selective, sensitive and efficient methods for preconcentration of trace amounts of metal ions including Cr(3+), Cu(2+)., Zn(2+) and Ni(2+) ions by incorporation of 2-hydroxy-(3-((1-H-indol 3-yle)phenyl) methyl) 1-H-indol (2-HIYPMI) on SDS-A has been reported. The proposed methods are based on the uptake of chelate of under study metal ions with these new ligands loaded on SDS-A. The influences of the analytical parameters including pH, ligand and SDS amount, eluting solution (type and concentrations) and sample volume on metal ions recoveries were investigated. The extraction efficiency was >95% with relative standard deviation lower than 5%. The method has been successfully applied for the extraction and determination of these ions content in some real samples. (C) 2011 Elsevier Ltd. All rights reserved.
