摘要：

The capillary electrophoretic separation of Fe(II), Cu(II) and Zn(II) ions in an acidic buffer solution (pH 2.5) by complexation with 1,10-phenanthroline is investigated. As 1,10-phenanthroline is a neutral ligand, the positively charged metal complexes formed migrate in the same direction as the EOF, providing a rapid separation of metal ions in acidic buffers. The method was applied to the determination of metal ions in vitamin tablets.
