英文摘要	The coordination interaction between saponified 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (HEHEHP) with lanthanide ions [Ln(III)] in an extracted organic phase has been studied by FT-IR spectral analysis. The result indicates that with the increase of lanthanide loading in the organic phase, the microstructure of the water/oil microemulsions formed by the saponified extractant is gradually destroyed. The P=O group of the extractant was found to coordinate with the Ln(III). The coordination ability of the lanthanide series with the P=O group was found to increase from La(III) to Pr(III), but decrease from Pr(III) to Lu(III).; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1997WW40400052&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Analytical; SCI(E); 0
