- Department of Chemistry, Shivaji University, Kolhapur-416 004 Manuscript received 29 September 1983, revised 30 May 1984, accepted 10 August 1984 Anion exchange chromatographic studies of CdII, znII, CoII, CuII, CalI, MnII MgII and NiII on Dowex 21 K (CI- form) in mixed solvent systems were carried out. The efficiency of acetone-trichloroacetic acid (TCA) system is evaluated in terms of distribution coefficients and suggested the following selectivity sequence, Cd \(\gg\)Zn > Co > Cu > Ca > Mn \(\approx\) Mg \(\approx\) Ni. Methods have been developed for the separation of Ca/Mn/Mg/Ni from Cd/Zn/Co in binary mixtures. Many Interesting sequential separations of metal ions from tertiary and quaternary mixtures are carried out. This ion exchange method is applied to the analysis of brass.
