摘要: Capillary electrophoresis of alkaline-earth metal ions was examined with a UV-absorbing chelating agent. The metal1 chelates separated in capillary were measured by on-column UV-absorptive detection. When ethylenediamine-tetraacetic acid (EDTA) used as an agent carrier solution (pH 9.2), the order migration time (t(m)) follows: Ba(2+)
