Membranolytic Activity and Morphological Characterization of Palygorskite and Sepiolite
The hormitic clays, palygorskite (attapulgite) and sepiolite, are being commercially used for many different applications. In 1983, approximately 1.1 million tons of palygorskite was used in industrial countries of the western world, as compared to 400,000 tons of sepiolite in 1984 (see IARC, 1987, for production, consumption, and application data). Concern about the potential health hazard of these minerals has arisen due to their fibrous nature and extensive application as asbestos substitutes (Bignon et al, 1980).
