Abstract
The phenomenon of isothermal supersaturation of solutions in a porous medium at ion exchange is studied on the basis of mathematical modeling. The phenomenon lies in the fact that the solution with concentration higher than the maximal solubility of the substance is formed in the pores of sorbent and no precipitation occurs. The question of why there is no precipitation in large pores or grain cracks is explored in this article. It is shown that the phenomenon under consideration can be explained not by changing of the thermodynamic conditions in the sorbent pores but by the effect of dynamic equilibrium between the aggregation of particles of the condensed phase in the inner part of the pores and their disintegration near the surface of the sorbent grains. The hypothesis proposed is verified by the quantitative studies based on simulation using the available experimental data.
