Extraction with organic solutions of 2-thenoyltrifluoroacetone (TTA) has proved to be a versatile and powerful method for radiochemical separations. A summary of the data in the literature is presented. In general, the logarithm of the extraction coefficient is linear with pH at constant TTA concentration. The slope of this linear relationship and the pH of 50 per cent extraction for 0.2 M TTA in benzene are presented for fonty-eight elements in the form of a periodic table. A graph is given by which one may quickly estimate per cent extraction as a function of pH. An equation for the variation of extraction with TTA concentration is given and the effect of changing the or ganic solvent is discussed. New experimental data are presented for the extraction of Pa(V) and Fe(III) from hydrochloric acid. (auth)
