Zeolitised materials of the mediterranean area as adsorbents for environmental protection

摘要

An investigation on the adsorption properties of zeolite-rich rocks, coming from deposits located around the Mediterranean basin, has been carried out, in view of their possible utilisation in the field of environmental protection. Samples investigated contained chabazite, phillipsite, clinoptiololite, mordenite and faujasite and came from different formations in central Italy, north-eastern Greece and north-eastern Jordam. After a careful chemical and mineralogical characterisation of the samples, adsorption isotherms of H_2O, CO_2, SO_2 and NH_3 at 25 deg C have been obtained.
