Mathematical model of the dynamics of sorption in the ion exchangers layer

Abstract

A kinetic equation of the upgraded Thomas model adequately described the degree of component
extraction on the duration of contact solution with a layer of ion exchanger, which takes into account the
effect on the dynamics of the diffusion resistance in the layer channels and ion exchanger grains in the
column with a fixed load. The possibility of the model of one-dimensional capillary flow using to
measure the diffusion resistance at moving fluid in the channels of the ion exchanger layer. Retrieved
