Chemical Equilibrium in a Protein Adsorption Ion-exchanger

Model ID: 1397


This example uses algebraic equilibrium relations to model the time-dependent adsorption of proteins to an ion-exchange medium.

The fluid phase contains three components: two proteins and one salt. The adsorption/desorption kinetics are described by a set of equilibrium reactions where proteins displace ions adsorbed at the surface and vice versa.

The model highlights the implementation of reactions at chemical equilibrium in mass-transport modeling by setting up the balance equations describing the present diffusion/reaction system results in a system of six partial differential equations.
