摘要：

Simple and rapid experimental techniques are developed and demonstrated for obtaining fundamental data for use in analyzing complex industrial ion-exchange systems. A system consisting of a microreticular polymeric resin (Dowex 50Wx8) and solutions of ethylenediamine dihydrochloride and ammonium chloride was used. This typical amine wastewater stream exhibits a number of the major complexities associated with industrial systems. Equilibrium relationships, ionic diffusion coefficients in the resin, dispersion coefficients, boundary layer thicknesses, ion-exchange capacity, bed void fraction, and particle dimensions were determined experimentally. These data were then used in a model and gave good agreement with observed breakthrough curves. © 1979, American Chemical Society. All rights reserved.
