Abstract

A low temperature Mössbauer study of a series of membranes has been made to determine the distribution of ions in them. The presence of three types of iron species has been observed: (1) small units (A) or monomeric species with d <30 Å; (2) ferric dimers (B) bridged by oxygen or hydroxyl ions; (3) clusters (C) of variable sizes. The percentages of the various species as well as the average size of clusters were evaluated from these spectra.
