Conditions for the isocratic separation by reversed-phase ion-interaction chromatography of Bi(III), Fe(III), Co(III), Ni(II), Cu(II) and Pb(II) chelates with ethylenediaminetetraacetic acid have been studied using UV-Vis detection. Both chromatographic and spectrophotometric conditions for the determination of these metal chelates are discussed including ion-interaction reagent concentration, water/methanol ratio, ionic strength, pH and absorbing wavelengths. Detection limits are particularly satisfactory for Bi(III), Fe(III) and Co(III) chelates.

Abstract
Conditions for the isocratic separation by reversed-phase ion-interaction chromatography of Bi(III), Fe(III), Co(III), Ni(II), Cu(II) and Pb(II) chelates with ethylenediaminetetraacetic acid have been studied using UV-Vis detection. Both chromatographic and spectrophotometric conditions for the determination of these metal chelates are discussed including ion-interaction reagent concentration, water/methanol ratio, ionic strength, pH and absorbing wavelengths. Detection limits are particularly satisfactory for Bi(III), Fe(III) and Co(III) chelates.
