The use of chromatographic columns filled with Kel-F (poly- trifluorochloro-ethylene) supporting concentrated solutions of tri-n- octylphosphine oxide (TOPO) in cyclohexane was investigated. After selecting the best way of preparing the coiumns, examples are given of the following separations: Fe/sup 3+/ - Co-Ni-U/sup 6+/, V/sup 4+/- Ti/sup 4+/ - U/sup 6+/, Mn - CuU/sup 6+/; Al- Cu- Fe/sup 3+/- U/sup 6+/ and Fe/sup 2+/ - Fe/sup 3+/. Short colu mns of Kel-F/TOPO were also used for the isoiation and quantitative determination of traces of elements in dilute solutions and in the presence of large amounts of foreign ions. The following examples are discussed: Fe and Co in Ni, U and Th in the presence of 13 foreign ions and Zr in Cu. (auth)
