Abstract
The isotachophoretic separation of trivalent metal complexes of some polyaminopolycarboxylic acids in acetone-water solvent has been carried out. The variation of the qualitative index, RE, obtained by analysis of the isotachopherograms resulted in a classification into two groups: FeIII, CoIII, InIII and BiIII complexes, and AlIII, CrIII and GaIII complexes. The satisfactory separation of trivalent metal ions was accomplished by employing a polyaminopolycarboxylic acid as the terminating electrolyte. Linear calibration graphs were obtained in the range 2 × 10–5–2 × 10–4 mol dm–3, the injection volume being kept constant at 25 µl.Keywords
