Abstract: The mechanism of ion exchange reaction of metal ions on Stannic selenopyrophosphate (SSPP) and the characteristics of exchange reactions on SSPPwere studied by means of the determination of surface ion exchange capacities and IR, Reflection Spectra and ESR. The mechanism was applied to explaining the selectivity sequences of ions on the exchanger.

Key words: Inorganic ion exchanger, Stannic selenopyrophosphate, Mechanism of ion exchange, Selectivity of ion exchange
