Abstract
The synthesis of a composite membrane material on the basis of cation-exchange membrane MK-40 with inserted particles of acid zirconium phosphate is realized. It is shown that zirconium phosphate in the membrane's matrix takes on the form of small amorphous particles and is uniformly distributed. The obtained membrane is characterized by large values of conductance and diffusion coefficients for cations and anions, as well as by a lower selectivity when compared with the initial analogue. It is shown that the basic reason for this is the increase in the size of pores and channels, which are filled in the course of experiment by a solution of an electrolyte.
