Separation of metal ions as chelates of 1N2, 7O3, 6S In the presence or abssence of tba~+ by capillary electrophoresis

摘要

Separation and determination of metal ions based on the formation of chelate anions with 1-Ni- troso-2, 7-dihydrexynaphthalene-3, 6-disulfonic acid (1N2, 7O3, 6S) was studied by using HPCE of the nine metal ions examined, the ions that can be detected sensitive- ly with 1-Nitroso-2, 7-dihydrexynaphthalene-3, 6-disul- fonic acid were Fe~2+, Co~2+, Cu~2+, Ni~2+, Zn~2+ and Pd~2+.
