Simultaneous preconcentration and determination of copper, nickel, cobalt and lead ions content by flame atomic absorption spectrometry
M Ghaedi, F Ahmadi, A Shokrollahi - Journal of hazardous materials, 2007 - Elsevier
A sensitive and simple method for the simultaneous preconcentration of nutritionally
important minerals in real samples has been reported. The method is based on the
formation of metal complexes by 4, 6-dihydroxy-2-mercaptopyrimidine (DHMP) loaded on
activated carbon. The metals content on the complexes are then eluted using 5mL 2M HNO3
in acetone, which are detected by AAS at resonance line. In this procedure, minerals such
as Cu, Ni, Pb and Co could be analyzed in one run by caring out the simultaneous …

A sensitive and simple method for the simultaneous preconcentration of nutritionally
important minerals in real samples has been reported. The method is based on the
formation of mineral complexes with n-benzoyl-n-phenylhydroxylamine (NBNPHA),
supported on sodium dodecyl sulfate (SDS)-coated alumina. The metals from the complexes
are then eluted with 5 mL of 5 M HNO3, and detected by AAS. Minerals, such as Cu, Ni, Pb
and Co, could be analyzed in one run by carrying out their separation and quantification …
