Modeling and research of acids and salts sorption separation process in the solution

On the basis of mathematical modeling and experimental results mechanism of “Acid retraction” effect in sorption separation of nitric acid and nitrates of various metals is studied. The method of determination of dielectric permeability and concentration of molecules and ions in the sorbent phase of electrolytes is offered. The model describing the complex of available experimental dependences with good accuracy is constructed. Results of modeling and their comparison with the empirical data are presented. The contribution of the various physical factors defining change of sorbent capacity is analyzed.
