Exclusion chromatography of metal chelates

The chromatographic behaviour of ethylenediaminetetraacetate complexes of cobalt(II), nickel(II), copper(II), chromium(III), iron(III), cobalt(III) and bismuth(III) on Sephadex columns has been investigated by Deguchi [ref. 68]. 

The elution volumes were dependent on the pH values of the eluent the varia-
