Abstract

M??ssbauer spectra of octahedral Fe3+ in NAu-1 nontronite, saturated with Na+, K+, NH4+, Ca2+ and La3+ have been analysed as two quadrupole doublets. The interlayer cations were found to affect the mean isomer shift, the quadrupole splitting and the spectral area. By considering the statistically significant nearest cation neighbour coordination environments, the inner doublet has been assigned to an octahedral Fe3+ surrounded by three Fe3+ in the octahedral sheet and eight Si4+ in the tetrahedral sheets. The outer doublet is due to the same octahedral coordination, but combined with [7Si4+, 1Al3+] and [6Si4+, 2Al3+].

Conference

Conference	International Symposium on the Industrial Applications of the Mossbauer Effect 2009
Abbreviated title	ISIAME 2009
Country/Territory	Austria
City	Vienna
Period	19/07/09 → 24/07/09
Other	All papers were peer reviewed. The ISIAME symposium is concerned with the application of a nuclear technique, Mössbauer Spectroscopy, to investigate industrially related problems. This technique yields information on certain elements in the solid state, with iron being the most rewarding element. Since iron is an abundant element with many important uses, the reader of these Proceedings will find on its pages a large variety of contributions devoted to such diverse areas as catalysis, magnetism, biology and planetary science (e.g., studies of minerals on the surface of Mars).
