摘要：

The state of iron in natural zeolites is an important feature for the practical applications of these materials. A Mössbauer study, complemented with other methods, of iron-containing zeolitic rocks from several countries (Mexico, Cuba, Czechoslovakia, and the USSR) was developed. It has been determined that iron is located as high spin Fe3+ in framework tetrahedral sites, in extraframework octahedral sites as free Fe(H2O)63+, and as high spin Fe2+ in octahedral coordination in extraframework sites or in another aluminosilicate associated with the zeolite. Iron is also located in magnetite contained in the zeolite rocks. © 1990.
