Hybrid organic-inorganic ion exchangers are obtained by incorporating amorphous zirconium hydrophosphate into the gel of strong acidic cation exchange resin. Hybrid organic-inorganic ion exchangers are obtained by modifying strong acidic cation exchange resin with amorphous zirconium hydrophosphate. The synthesized materials are studied by standard porometry contact. It is found that raising the inorganic component content to 34 wt % diminishes the microporosity of the samples and simultaneously enhances the of meso and macropore volume. Experiments establish that modification of a polymer matrix lowers the self diffusion coefficient of Ni 2+ from 8.1 × 10 -12 to 2.4 × 10 -12 -4.1 × 10 -12 m 2 s -1 ; nevertheless, an inorganic ion exchanger minimizes the inhibitory effect of co ions on the Ni 2+ → H + exchange rate. One possible mechanism for of filling of the matrix by with particles of zirconium hydrophosphate is discussed.
