Abstract

The separation of neutral copper, manganese, cadmium, and nickel chelates of Schiff base ligand, N,N’- Bis(salicylidene)1,3-propylenediamine is reported on a column of silica. Metal chelates 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 350nm.
