Simultaneous Determination of Inorganic Anions and equally Charged Complexes of Transition Metals with Polyaminocarboxylic Acids by Capillary Electrophoresis
High efficiency Capillary Electrophoresis (CE) separation (440–760 thousand theoretical plates per meter) of metal-edta complexes and inorganic anions has been demonstrated using Kinetic Differentiation mode-Ion-Exchange Electrokinetic Chromatography (EKC). An aromatic homolog of polyaminocarboxylate (Quin 2, see Figure 1) has been used for the increase of the detection sensitivity. The detection limits of transition metals were found in the range of (0.59–1.90) × 10<SUP>−6</SUP> M (M = mol dm<SUP>−3</SUP>).
