是一種鋁鹽成、無色無味的晶狀物質，可溶於水中，具有很好的收斂及止血功能，也具止汗功能，很多止汗劑也會添加明礬的成分.可加入葡萄柚萃取液、甘油、純水做收?水。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
報道了由正負離子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離及分析的新型雙水相萃取體系.研究了正負離子表面活性劑（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醇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.通過在高聚物分子中接上親和配基，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鹽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At the same time, solid - phase microextraction ( spme ) as a new solvent - free extraction technique in sample preparation appeared in early 1990s. because of its advantages of simplicity, rapid extraction and easy quantification, spme was successfully applied to extraction and concentrating of many compounds in environment, food, biological fluids and pesticide matrices, the samples included gas, liquid and solid. spme could be easily utilized with gas chromatography ( gc ) and high performance liquid chromatography ( hplc )
固相微萃取（ spme ）是由pawlisayn在1990年提出的一種新型的無溶劑樣品處理技術，在與氣相色譜（ gc ） 、高效液相色譜（ hplc ） 、毛細管電泳（ ce ）以及紫外光譜（ uvas ）等聯用后，廣泛應用於水、土壤、空氣等環境樣品和血、尿等生物樣品，以及食品、藥物等樣品的分析測定。
