全氟碳化合物乳液中氧溶解度测定的改良酶促法
Determination of Oxygen Solubility in Perfluorocarbon Emulsions by a Modified Enzymatic Method
摘要
Abstract
Oxygen solubility in perfluorocarbon(PFC)emulsions is a crucial performance metric in fields such as artificial blood,oxygen transportation and diagnostic imaging agents.However,there is a lack of simple and accurate detection methods.In this study,the perfluorooctyl bromide(PFOB)emulsion was prepared by using perfluorohexylethyl polyoxyethylene ether(FEO)as the emulsifier,and a modified enzymatic method was developed by using a more stable Orange G as the color indicator to determine the oxygen solubility in the PFOB emulsion at 298.15 K and atmospheric pressure.For 0.2 mL emulsion,the oxygen solubility measured by the modified enzymatic method was close to that measured by gas-liquid chromatography as reported in the literature.The effects of mass fractions of PFC and FEO in the emulsions on the oxygen solubility were studied based on the modified enzymatic method.The results indicate that the oxygen solubility in the emulsion increases with the increasing mass fraction of PFC,independent of the mass fraction of the emulsifier.关键词
