P. Ganguly et al., EXCHANGE OF INTERLAMELLAR CATIONS WITH ITS AQUEOUS ENVIRONMENT IN CHARGED LAYERED SYSTEMS - SIMILARITY BETWEEN CLAYS AND LANGMUIR-BLODGETT-FILMS OF METAL-SALTS OF FATTY-ACIDS, Langmuir, 10(6), 1994, pp. 1670-1672
The general principle involving the exchange of interlamellar cations
in clays with those in its aqueous environment has been examined in th
e case of Langmuir-Blodgett films of metal salts of fatty acids. X-ray
diffraction as well as X-ray photoelectron studies on Langmuir-Blodge
tt films made up by sequential deposition from two troughs containing
various metal ions with the same fatty acid condensed Langmuir monolay
er have been studied. Evidence is presented for the first time of the
exchange of metal ions between the interlamellar spaces of the negativ
ely charged fatty acid bilayers with those in its aqueous environment.
