THE EFFECT OF POLYOXOMETALLATE COMPLEXES OF NICKEL AND COPPER ON THE RATE OF THEIR HETEROPHASE REACTION WITH AMMONIA

was established that the compounds formed by the cations in amine complexes of nickel(II) and copper(II) and the anions of polyoxometallates are capable of reacting stoichiometrically with gaseous ammonia when in the hydrated state. Some of the studied compounds are characterized by high sorption capacity (up to 40 molecules of adsorbate to a formula unit of the complex) and exhibit selectivity in the sorption of ammonia in the presence of water vapor.
