Abstract:Equations for equilibrium constants of ion exchange between fatty acid monolayers and subsolution counterions are derived. The approach of Matsubara et al. [4], where the monolayer is considered as a two-dimensional regular mixture is employed, but the different molar volumes of its components are taken into account. Using the equations obtained the Kex values are calculated on the basis of published data on the monolayer composition in the systems Cd2+/HArch, Ba2+/HArch, Ca2+/HSt, pb2+/ HSt and Cu 2 +/HSt. Th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
