  4. A novel aqueous two - phase system can be formed by the mixtures of a polymer and cationicanionic surfactants. such a system can be used as a partitioning system of proteins. in this work, we investigated the formation, phase behavior and protein partitioning in aqueous two - phase systems formed by dodecyltriethylammonium bromide / sodium dodecylsulfate / peg and dodecyltriethylammonium bromide / sodium dodecylsulfate / dextran. the ligands with affinity were attached to the polymers and the affinity partitioning of proteins was investigated. it was shown that the surfactants and polymers are enriched in different phases of aqueous two - phase systems. phase separation are promoted by increasing temperature and adding inorganic salts. different proteins are partitioned in different phases. the selectivity of protein partitioning is increased by adding ligands with affinity

    報道了由正負表面活性劑與高聚物混合溶液形成的一種可用於蛋白質的分及分析的新型雙水相萃取體系.研究了正負表面活性劑(溴化十二烷基三乙銨/十二烷基硫酸鈉)分別與葡聚糖和聚乙二混合雙水相體系的形成規律、相行為及牛血清蛋白和溶菌酶在雙水相體系中的分配.通過在高聚物分中接上親和配基,研究蛋白質在雙水相體系中的親和分配.結果表明,在該體系中,表面活性劑與高聚物分別富集於不同相中.升高溫度及加入無機均可促進雙水相體系的形成,不同蛋白質可分配于不同的相中.親和配基的引入極大地增強了蛋白質分配的選擇性
  5. When using the method of periodically renewing electrolyte, the average current efficiency is 47. 3 % ( ii ) the solubility of k2feo4 in the solution of naoh is higher than that of the same concentration of koh solution and both of them become low with the growth of the alkaline concentration. the solubility of k2feo4 in the mixed solution of koh and naoh was influenced by both of common ions effect and salting - out effect and the influence of common ions effect is more heavy. the rate of methanol ' s reacting with k2feo4 is proportional to the content of water in the solid k2feo4. the stability of the potassium ferrate solution is far below the solid
