CATION-EXCHANGE ELUTION SEQUENCES. I. DIVALENT AND RARE-EARTH CATIONS WITH EDTA, HEDTA AND CITRATE
Ion exchange elution sequences were established for some divalent and trivalent ions in elutions with those eluants commonly used for the separation of macroquantities of the rare-earth elements --- ethylenediaminetetraacetic acid (EDTA), hydroxyethylethylenediaminetriacetic acid (HEDTA), and citric acid. The order of elution of the sequence of trivalent metal ions was found to shift with respect to the sequence of divalent metal ions when the pH of the EDTA eluant was changed and as the composition of the separating mixture changed. A theory is presented which is of qualitative value as an aid in the description of the elution of polyvalent cation mixtures with chelating eluants. (auth)
