英文摘要	The formulations of the purity gradient and accumulation were proposed, and their relationships with purity distribution were studied in two-component countercurrent extraction system. By the static and dynamic simulation, the purity distribution curves with various feed composition and separation factor were interrelated, and the related purity gradient and accumulation were calculated. The results show that there are purity gradient maxims in extraction and scrubbing sections for each component in both aqueous and organic phases. The accumulation of each component in both phases increases with its content in the feed. Meanwhile, its absolute value of purity gradient decreases in extraction section and increases in scrubbing section. Furthermore, the purity gradient and accumulation as the monitoring parameters for automation were evaluated. The precision of the on-line analysis in the sensitive point and the range of accumulation were also estimated.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000081227700002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Applied; SCI(E); EI; 3; ARTICLE; 2; 84-87; 17
