摘  要:4通过拆除表面活性剂胶束实现分离 汽提和溶剂萃取两种方法都可以从表面活性剂胶束中除去有机化合物,同时使胶束完好地留在水溶液中;另一方面,如果溶液中表面活性剂分子胶束耗尽,有机化合物将会处于过饱和状态并与水相分离。水相中的有机化合物将会是水溶状态,可以与表面活性剂单体共存(在cmc状态),一旦所有的胶束被除去,可能会实现净化流的排放。胶束的拆除会降低表面活性剂浓度,同时实现胶束增溶有机化合物的相分离。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.
