Abstract

Physico-chemical properties of cation- and anion-exchange resins are studied after a long
operation period in industrial natural water deionization systems. It is found that humic acids contact with
the phase of the anion-exchange resin leads to a decrease of internal diffusion coefficients for mineral
ions and to an increase of the internal diffusion stage impact to the total mass transfer velocity. Therefore
one can observe the deterioration of the kinetic properties of ion-exchangers and the decrease of their
working exchange capacity in the solutions containing humic acids.
