Abstract

The effects of nonlinear equilibrium and axial mixing on sorption processes in packed ion exchange resin beds have been studied by digital computer simulation of column performance. Results show clearly that the presence of these effects leads to false estimates of apparent intraparticle diffusivities when a linear model is used in analyzing data. A technique for estimation of true diffusivities from apparent values is presented.
