Abstract
Capillary electrophoretic behavior of ketones and beta-diketones was e xamined using anionic, nonionic and cationic oil in water (o/w) microe mulsions as separation media, containing naphthalene as a fluorophore for means of indirect fluorescence detection. The migration behavior w as greatly dependent on the charge type of microemulsions as well as o n the composition and pH, Among the systems examined, sodium dodecyl s ulfate (SDS) microemulsions were the most advantageous because of the wider separation window, the higher dissolution capacity and the rapid distribution rate. Capacity factors of the solutes in the electrophor esis employing sos microemulsions were correlated to the distribution and interfacial adsorption parameters determined in bulk two-phase sys tems.
