Abstract

The decision analysis problem of sorption, considering influence private diffusion resistance for
speed of sorption process by Me+ in a column with a motionless layer ion-exchanger is resulted. The
interval of values of factors of diffusion in ion-exchanger grains, excluding application of model of
Thomas is established. Possibility of using one-dimensional capillary current model for an estimation
diffusion resistance is shown at liquid movement in layer channels of ion-exchanger
