reagents are summarized and their positions in a new solvent extraction technology are discussed. In contrast to the familiar tributyl phosphate (TBP), the applications of which have been lioited to highly salted nitrate solutions, several other neutral and acidic or organophosphorus compounds have demonstrated the ability to extract uranium from a wide variety of aqueous solutions. Some of these reagents have reached and phosphate liquors. More generally, by proper choice of reagent it is now possible to extract uranium from nearly any solution in which it is encountered. In extraction of other metals, including vanadium, thorium, zirconium, hafnium, titanium, molybdenum, rare earths, and plutonium, and for separations of closely related elementss, including zirconium-hafnium, lanthanides, and actinides. Besides process applications, these physicochemical appliocations, some of which have already been developed. In additon to the comparisons of different reagent types, correlations with other properties and the effects of variation of structure within a reagent type are also discussed. These include both general and specific effects on extraction power, selectivity, and physical behavior, which are of sufficient magnitude to add significantly to the versatility of this wide range of solvent extraction reagents.
