    Notes: Summary Using reversed-phase high-performance liquid chromatography acetylacetonate complexes with trivalent metals such as Al(III), Co(III), Cr(III) and Fe(III) have been examined in columns containing RP-2, RP-8 and RP-18 bonded phases. The mobile phase consisted of acetonitrile/water or methanol/water mixtures with various compositions. As shown the order of elution of the acetylacetonates depends on the type of the column packing and on the nature and concentration of the organic modifier in the mobile phase.

    Separation of chlorophenols on a cation-exchanger in Ce(III) form (1984)
    Springer
    Chromatographia 18 (1984), S. 704-706 
    Details
    ISSN: 1612-1112
    Keywords: Ce(III) complexes ; Cation-exchanger in Ce(III) form ; Ion-exchange chromatography ; Chlorophenols

    Topics: Chemistry and Pharmacology
    Notes: Summary The separation of chlorophenols on Dowex 50 WX 8 200/400 mesh resin in the H+ form and in the M3+ form has been investigated using a mixture of aqueous sulphuric acid and organic modifiers (e.g. acetonitrile or isopropanol) as the eluent. It was shown that formation of Ce3+ complexes with chlorophenols is a more specific interaction than physical adsorption or phase partition. Full separation of the compounds examined was achieved by elution from a column with the resin in the Ce3+ form.
