Conclusions 1. New cation exchange forms of zeolites with various degrees of replacement of sodium by other cations have been synthesized and investigated. 2. A correlation has been established between the hydration capacity of exchange cations and the adsorbability of water vapors on the corresponding zeolite derivatives. 3. Exchange cations, which are active centers of adsorption, just like the composition and structure of the zeolite lattice, determine the specific interaction in the adsorption of molecules of various structures and electronic structures. 4. When sodium ions in type A zeolite are exchanged for calcium, cobalt, or nickel, the properties of the corresponding form of zeolite begin to be manifested at a degree of exchange equal to approximately 0.33, which is in good agreement with the theoretical calculations. 5. The stability of various cation exchange forms of zeolite to the action of theγ radiation of Co60 has been established, which profitably distinguishes zeolites from most of the organic ion exchange resins.
