N.B. Ferapontov *, V.I. Gorshkov, L.R. Parbuzina, N.L. Strusovskaya, A.N. Gagarin M.V. Lomonosov Moscow State University, Department of Chemistry, Leninskie Gory, GSP-2, 119992 Moscow, Russian Federation Received 18 March 2005; received in revised form 28 June 2006; accepted 19 August 2006 Available online 2 October 2006 Abstract This work deals with thermodynamic description of equilibrium between an ion exchange resin and the solution of low molecular weight electrolyte. The suggested approach allows calculating thermodynamic constant of ion exchange equilibrium. In order to calculate the activity of ion exchange groups in the resin having monoionic form we used published reference data […]

ОПИСАНИЕ МЕЖФАЗОВОГО РАВНОВЕСИЯ В СИСТЕМЕ ИОНИТ- РАСТВОР И ОПРЕДЕЛЕНИЕ КОНСТАНТЫ ИОНООБМЕННОГО РАВНОВЕСИЯ.

NB Ferapontov, AN Gagarin, NL Strusovskaya M. V. Lomonosov Moscow State University, Moscow Summary The equilibrium in systems composed of water, electrolytes and ionite is considered. The method of the description of properties and calculation of amounts of components in the phase of solution of cross-linked polyelectrolyte is represented. We propose two methods of definition of the thermodynamic constant of ion-exchange equilibrium. In the first variant, at the theoretical description of equilibrium the equation is obtained, from which follows, that the equilibrium constant can be defined as the ratio of constants of distribution of separated substances. In the second variant […]
