中文: 报道了由正负离子表面活性剂与高聚物混合溶液形成的一种可用于蛋白质的分离及分析的新型双水相萃取体系.研究了正负离子表面活性剂(溴化十二烷基三乙铵/十二烷基硫酸钠)分别与葡聚糖和聚乙二醇混合双水相体系的形成规律、相行为及牛血清蛋白和溶菌酶在双水相体系中的分配.通过在高聚物分子中接上亲和配基,研究蛋白质在双水相体系中的亲和分配.结果表明,在该体系中,表面活性剂与高聚物分别富集于不同相中.升高温度及加入无机盐均可促进双水相体系的形成,不同蛋白质可分配于不同的相中.亲和配基的引入极大地增强了蛋白质分配的选择性.

中文: 文摘:以双流体模型为基础,通过质量守恒方程和动量守恒方程的耦合,提出了液-液两相系中弥散传质的连续波模型.由该模型得到弥散传质过程阻塞和弥散传质过程弱不稳定性产生的条件,计算了液滴尺寸及其分布对乳化液极大堆砌分数的影响,解释了剧变型乳化逆变和渐变型乳化逆变现象.研究结果表明,乳化逆变是由于弥散传质过程的不稳定性而引起的悬浮体型态的改变,随液滴尺寸多分散性的增大,极大堆砌分数增大;随液滴平均尺寸的增大,多分散性对极大堆砌分数的影响减弱;当韦伯数足够大时,液滴尺寸及其分布对乳化液极大堆砌分数无影响.
