Research is being conducted on multicomponent ion exchange systems to:          compare ion equilibrium data on mixed reruns with a complex Langmuir            adsorption model and compare data on the dynamics of mixed media ion            exchange columns with predictions from the extension of the coherence           model of Helfferich and Klein.  The comparisons will verify or lead to          the development of models which can be used to design ion exchange              systems for such applications as the removal of ammonia from dialysis           fluid, contracting metal ions in hydrometallurgy, and chromatographic           separation of complex biological mixtures.
