Summary The thin-layer chromatographic behavior of a number of metal ions on ECTEOLA-cellulose has been surveyed in HCl media with and without an organic solvent such as methanol or acetic acid. The addition of a protic solvent to aqueous HCl solution enhances the adsorption of most metal ions tested. Ion-exchange and partition distribution were proposed as the mechanisms controlling the metal ion behavior on ECTEOLA-cellulose in HCl-protic solvent mixtures for the chlorocomplex-forming metal ions and for the other metal ions, respectively. Of the metal ions tested, Cd (II) shows a useful chromatographic distribution in aqueous HCl media, which has allowed the development of a very selective thin-layer chromatographic method for the separation of Cd(II) from other metal ions. Results are presented for the separation of Cd(II) from 38 other metal ions.
