Health implications of natural fibrous zeolites for the Intermountain West.

چکیده
Fibrous zeolites have recently been implicated in an endemic outbreak of malignant pleural mesothelioma in several villages in Cappadocia in central Turkey (Baris et al., 1979; Lilis, 1981). The possible association between fibrous zeolites and mesothelioma and the potential biological activity of fibrous erionite from the United States are under active investigation. The zeolite minerals comprise a group of over forty hydrated aluminum silicates. More than 300 probable deposits of the various natural zeolites are located in 25 states in the United States. Reserves of perhaps 10 trillion tons are present in the western United States; about 120 million tons are deposited near the surface (Sheppard, 1975). Several zeolites, including erionite and mordenite, may occur with a fibrous habit. Fibrous erionite is found in several well-defined deposits in Arizona, Nevada, Oregon, and Utah, where it occurs as thin, pure beds within sedimentary tuff sequences, or as outcrops in desert valleys of the Intermountain region.

Synthesis of Zeolites, Merlinoite Minerals of Damavand’s Natural Clinoptiloite Zeolites Mineral in Hydrothermal Conditions, under the Influence of Alkaline
In the present research synthesis of zeolites, merlinoite minerals of natural clinoptiloite mineral in the presence of alkaline mediums, was investigated. The analyzed variants are a result of a concentration of Na+ and K+ ions, temperature and time. Phase transition of clinoptiloite was conducted in the presence of an 8 molar potash solution (KOH) and a 4 molar soda solution (NaOH). Results in...

Zeolites A, X and HS were synthesized from natural Iranian Kaolinite by alkaline fusion,,followed by refluxing the mixture. The transformation of zeolites X to HS and Y to P were studied at different time intervals by X-ray diffraction and Scanning Electron Microscopy (SEM). It was revealed that in solution, zeolites HS and P are more stable than zeolites X and Y respectively

The main object of this study was to compare the natural and synthetic( NaA and NaM) zeolites as absorbents in removing emulsified and dissolved traces of organic compounds, which appear in the wastewater of power plants, refinery and petrochemical complexes. The specific objectives of the work was: a) to select the best species that have the highest amount of absorption; b) to measure th...
