从表面活性剂溶液中分离有机化合物的研究进展(待续)

Review of separation of organic compounds from surfactant solutions(to be continued)

总结了近年来从表面活性剂溶液中分离经乳化后的有机化合物的方法,综述了表面活性剂循环利用和表面活性剂—污染物处理的研究进展。从溶液中分离有机化合物或者表面活性剂主要有3种方式,分别是有机复合相间的传质、表面活性剂胶束拆除和控制表面活性剂溶液相行为。对上述3种方式以及其进行分离应用的优点和局限性进行详细说明,并表明就目前而言,基于质量传递将有机化合物分离到二次相的方法更为实用,最后对后期研究的两个重点问题进行了展望。

The recent development in separation of emulsified organic compounds from surfactant solutions has been summarized, and the research progress in surfactant reuse and/or surfactant contaminant disposal has been reviewed. Three major principles have been employed for separating organic compounds and/or surfactants from aqueous solutions, namely, organic compound inter-phase mass transfer, surfactant micelle removal and the manipulation of phase behavior of a surfactant solution. The details of these principles and their applications are discussed, with the advantages and limitations of each separation method being introduced. Separation based on mass transfer of the organic compounds into a secondary phase is currently more practical than the others. Finally, two major issues requiring further research are identified.
