Abstract
Cation exchange taking place in Langmuir-Blodgett films of fatty acids deposited on hydrophobic Cu substrates was investigated by plasma des orption and spontaneous desorption mass spectrometry. Complete cation exchange was found in plain arachidic acid monolayers. Incomplete exch ange was found in bilayer and multilayer films of Cd arachidate with t hicknesses up to 10 monolayers. The fraction of exchanged ions is inde pendent of the number of layers.
