| Abstract | Solvent extraction is a technique which has been highly developed within many national nuclear energy programs because of its suitability as a selective separation process for fission products, actinides, and other radioactive substances. The technique is briefly described in several sections of this book (§§ 5.5.3, 9.2.6, 9.4.3, 15.7.4, 16.3.3, 21.7, and especially in 21.6 on the Purex process). It is based on the formation of uncharged organic metal complexes which are preferentially soluble in organic solvents. The three main types of such compounds are: (i) organic chelate (i.e. binding through two positions in the organic molecule, like a claw) complexes such as plutonium tetraacetylacetonate, PuAa (general formula MA ), §9.4.3, cf. 4 n Figs. 9.3, 9.9. and 9.11; (ii) inorganic metal complexes forming adducts with solvating organic compounds like TBP and hexone, e.g.UO (NO ) )(TBP) (or generally ML S , where L is an inorganic anion and 2 3 2 2 n s S the organic adduct former, §21.6, cf. Fig. 16.8); (iii) ion pair complexes between large organic cations (like alkylammonium ions, R NH ) and 3 + |
