abstract An enzymatic method to measure the glucose content in solution was adapted for measurements of oxygen content in oil in water emulsions with a precision of about 1%. The oxygen solubility in concentrated perfluorocarbon in water emulsions at 310.2 K and atmospheric pressure was measured. To study the effect of the perfluorocarbon and of the surfactant in the oxygen solubility, two perfluorocarbons, n-perfluorohexane and perfluorodecalin, in combination with three nonionic surfactants, Lecithin, Span 20 and Pluronic F-68 were used. The concentrations used were 50% (w/v) for the perfluorocarbons and 5% (w/v) for the surfactant. The oxygen solubility is shown to be independent of the surfactant used and dependent only of the perfluorocarbon employed in the emulsions studied. © 2005 Elsevier B.V. All rights reserved.
