Abstract:
The separation of Fe(II), Ni(II), Ca(II), and Mg(II) chelates of Schiff base
ligand, N,N’- Bis(salicylidene)1,3-propylenediamine is reported on a
column of silica. Metal chelates are well resolved with good peak shape and
efficiencies when the mobile phase is linear gradients of Methanol in an
aqueous sodium acetate (50mmol/L, pH 5.40), using diode-array detector at
240nm. The ligand N,N’-Bis(salicylidene)1,3-propylenediamine N,N’-
Bis(salicylidene)1,3- propylenediamine, N,N’-Bis(salicylidene)-2,2-
dimethyl-1,3-propylenediamine, and N,N’ Bis(2-Hydroxyacetophenone)-
2,2-dimethyl-1,3-propylenediamine have been separated in order to choose
the ligand used for metal separation
