摘要
IN the early 1980s, Wu and co-workers indicated that the saponification of acidic extractants,such as di(2-ethylhexyl) phosphoric acid (D2EHPA), 2-ethylhexyl phosphoric acid mono 2-ethylhexylester (PC88A), and naphthenic acid (NA), is a process of the formation of a wa-ter-in-oil (w/o) microemulsion in the organic phase. From then on, the aggregation behav-ior of this sort of extractant and metal-extractant complex in bulk phases has been investigatedfor about twenty years. The microstructure and properties of organic aggregates were ex-
