Status Quo and Trend of Aqueous Two-phase Extraction and its Application

Aqueous two-phase extraction was a sort of highly active and new isolation technique. It was wildly used in biochemistry, pharmacy, analysis and survey of the sample and in analysis of singular metal. Especially in the biochemic separate industry, the aqueous two-phase extraction was obviously superior to the conventional extraction and separated methods. The basic principle features and application of the aqueous two-phase extraction was introduced. The related technology integrated with the ATPE and the thermodynamic model of ATPE was also mentioned. Its directions in the future and some unresolved problems were pointed out.
