【摘要】在308.15K下,研究了表面活性剂琥珀酸二（2-乙基己基）酯磺酸钠（Aerosol-OT,简称AOT）的浓度和水的含量不同时,溶解的CO₂对反胶束溶解牛血清蛋白（BSA）的性质和异辛烷中AOT反胶束稳定性的影响.实验表明,在适当条件下,CO₂可以使反胶束溶液中的蛋白质全部析出.本研究对有关机理进行了初步分析.更多还原

【Abstract】 The effect of dissolved CO2 on the solubilization of bovine serum albumin (BSA) in the reverse micelles of bis (2 - ethylhexyl)sulfosuccinate( AOT) in isooctane and the stability of the reverse micelles were studied at different AOT concentrations and water contents. It was found that the concentration of the surfactant and the water content in the reverse micelles significantly affected the solubilization of BSA. Most of the BSA in the reverse micelles could be precipitated under suitable conditions, and the mechanism was discussed.更多还原
