Study of Absorption Properties of Modified Zeolites

Natural zeolites from Armenia modified by chemical treatment and electron irradiation were studied for water and benzene vapor absorption and structural change. A significant influence of irradiation on the sorption property of zeolites was obtained: with increase of the irradiation dose the sorption of water vapors increased, while for benzene vapors it changes slowly. The results are discussed in terms of structural change and charge state variations induced by irradiation in the zeolite framework.
