THE CORRELATION OF CATALYTIC ACTIVITY OF CHELATING ION-EXCHANGE RESINS WITH SORPTION AND HYDRATION ENERGIES

The catalytic activity of sorbate complexes of some transition metals and its dependence on the metal ion content in chelating ion-exchange resins containing phosphoric (KRF-5p) and aminophospohonic (ADF) acid groups is investigated. The sorption energies of metal ions, as well as the hydration energies of resins containing metal ions, are determined over the entire range of coverages. The dependence of the hydration energy on the catalytic activity is found for the reaction of hydrogen peroxide decomposition. It is shown that the metal-ion concentration in the ionite affects the structure of sorbed complexes.
