Zeolites are microporous aluminosilicate minerals commonly used as commercial adsorbents and catalysts The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt who observed that rapidly heating the material believed to have been stilbite produced large amounts of steam from water that had been adsorbed by the material

eighteenth century and they are now known to be widespread in a variety of geological environments Zeolites may occur naturally as authigenic minerals formed from volcanic glass and various rock-forming minerals by interaction with aqueous solution or fluid in many geochemical environments (Breck 1974 Mumpton 1977 Gottardi and Galli 1985 Hay 1986 Boles 1988) More zeolite species
