Capillary zone electrophoretic studies of ion association between inorganic anions and tetraalkylammonium ions in aqueous–dioxane media. Journal of Chromatography A, 1069(2), pp.261-270.http://hdl.handle.net/20.500.11810/3199Full text can be accessed at http://www.sciencedirect.com/science/article/pii/S0021967305002499Ion association between inorganic anions and symmetrical tetraalkylammonium ions, R4N+ (R = Me, Et, Pr, n-Bu, n-Am, and 2-methyl butyl {isoamyl = iAm}) was investigated using ordinary silica capillary by capillary zone electrophoresis. An improved version of the Williams-Vigh method was used for the first time to measure the mobilities of the inorganic anions. Plots of log Kass against log dielectric constant in various media, revealed a smaller change in Kass compared to dielectric constant. These plots suggest that the Bjerrum's equation is inadequate in accounting for the associations of ions in a CZE setup.enAqueous–dioxane mediaWilliams–Vigh methodIon associationCapillary zone electrophoresisJournal Article10.1016/j.chroma.2005.02.009 · Source: PubMed
