Mathematical modeling of the separation of acids and salts in the solution by sorption’s method of "retention acid"
Analysis of possible mechanisms of the effect of acid retardation is carried out with using the method of mathematical modeling and experimental results on the separation of nitric acid and nitrates of various metals from mixed binary solutions on the nitrate form of strong base anion resin. A method of calculating the dielectric constant and the degree of dissociation of the electrolyte in the sorbent phase is proposed. A mathematical model describing the existing experimental results is developed and the contribution of different factors into capacity toward acids is estimated.
