Abstract: The enrichment behaviors of sodium dodecylsulfate (SDS) and bovine serum albumin (BSA) in SDS/BSA mixed aqueous system have been studied by the method of foam fractionation. The effect of the interrelation of the two components at the air/Wator interface on foam behaviors has been discussed. The experimental results indicated that the foam properties and enrichment in mixed systems were different from that in the system that two components alone. At low SDS concentration,the enrichement ratio of SDS and BSA were higher by foam fractionation; at high SDS concentration the enrichment ratio of the two components were reduced.

摘要： 借助泡沫分离法对阴离子表面活性剂十二烷基硫酸钠（ＳＤＳ）、牛血清白蛋白（ＢＳＡ）混合体系中，两种表面活性物质的富集行为进行了研究，并讨论这两种成分的存在对泡沫行为的相互影响。结果表明阴离子表面活性剂和蛋白质混合体系的起泡性能及各成分在泡沫中的富集不同于二者单独存在时的体系；表面活性剂浓度较低时，在泡沫分离中蛋白质和表面活性剂的提浓率较高：而表面活性剂浓度较高时，蛋白质和表面活性剂的提浓率均降低。
