“…Because of limited solubility, 10 ions [Au(III), Ir(III), Nb(V), Os(IV), Pa(V), Pd(II), Pt(IV) Sn(IV), Ta(V), and Zr(IV)] were added as chloride or fluoride complexes, some of which tended to extract from all media. This effect has been noted in the last column of Table I and it is important to interpret the distribution data in Figures 1 through 5 correctly.…”

The distributions of 57 metallic ions have been measured for three quaternary amines, tetrapropyl, tetrabutyl, and tetrahexyl, into methyl isobutyl ketone from five media, HNOs, H2SO4, HF, HCI, and NaOH, over the concentration range of 0.2 to 5N. Distribution data are presented as plots of per cent extraction vs. normality in a series of 5 periodic charts. Many separations for radiochemical and general analytical application are

“…As a result of this study, possible methods are presented for the separation of U and Pu from certain fission products. Maeck et al (71) have developed a highly selective extrac tion method for uranium using aluminum nitrate, tetrapropylammonium nitrate in an acid-deficient solution, and hexone as solvent.…”

The last several years have seen a reawakening appreciation of the value of solvent extraction separations processes both on analytical and process scales. Separations by solvent extraction are simple, convenient, clean, and applicable equally well to carrier-free tracer and macro amounts of materials. They usually require apparatus as uncomplicated as a separatory funnel and may readily be adapted to remote handling procedures.A variety of separations techniques have been applied to the problems of isolation and radiochemical purification of nuclides. General descriptions and recent surveys of radiochemical separations can be found in references (1) through (5). Although all of the separation methods mentioned are of great importance to the radiochemist, solvent extraction is particularly well suited to the purification of many radioisotopes since, after several extractions of a substance, the final product is usually relatively free from extraneous im purities which may be present when other separation procedures are em ployed. Also, if the isotope of interest has a short half life, a rapid separation is essential and extraction procedures have proved invaluable. Most of the extractions employed in radiochemistry are based on previously developed conventional analytical extractions, and the recent book by the authors (6) offers a comprehensive treatment of the subject of extraction as applied to inorganic analysis. In addition to covering the principles and practical as pects of the technique, procedures for the extraction of the elements are presented. The review by the authors (7) in Analytical Chemistry surveys the latest developments in the field. CLASSIFICATION OF SOLVENT EXTRACTION SYSTEMSMost metal salts are strong electrolytes that are relatively insoluble in organic solvents and soluble in water because of its ability to solvate the ions as well as because of its high dielectric constant. Since it is usually necessary to transform the hydrated metal ion into an uncharged complex in order to extract it into an organic solvent, it is convenient to classify metal extraction systems on the basis of the nature of the extractable metal 1 The survey of literature pertaining to this review was completed in December, 1958.2 Among the abbreviations used in this chapter are: EDTA (ethylenediamine tetraacetic acid); HDGP (dioctylphenyl orthophosphoric acid); TBP (tributyl phos phate); TTA (thenoyltrifluoracetone).
