✦ Synopsis

A simplified solution for multispecies ion exchange kinetics based on the Nernst-Planck model has been developed. The numerical solution has been tested by simple isotopic exchange and binary ion exchange kinetic solutions as well as with the Hwang's computed three-component ion exchange kinetic curves. All of these tests resulted in good agreement. The computational algorithm has been built in a program for the computation of multicomponent fixed bed ion exchange breakthrough and co-and counter-current elution curve. The details of this program will be reported elsewhere.
