Relative elution peak position of actinides and other ions in various HC1 concentrations. The positions of the Pu ions have been connected by lines. 117 eluted at all under the conditions of the experiment. A plot of the elution position of the tetravalent actinides under slightly cliff erent conditions is shown in Fig. 41 to show the relative elution position of Th(IV). The well-known separation of the trivalent actinides and lanthanides is illustrated by the increase in the elution positions of the lanthanides at high acidities. Nelson et al. 300 summarized the cation exchange behavior of most of the elements in HC1. The summary is in Fig. 42 as a periodic table of Dv vs HC1 concentration Dowex- 50 X 4 resin was used. Although relatively few data for Pu are included, the curves fo~ Th(IV), U(m), and Am(m) Permit a norm~ization to the data 117 of Diamond et al. Strelow 3’5 investigated the cation exchange behavior of 43 elements on Dowex-50 X 8 resin at HC1 concentrations up to 4 M with results in general agreement — with those above. He arranged the elements in decreasing order of the equilibrium distribution coefficients in 1 ~ HC1. The values ranged from 7250 for Zr(IV) to 0.3 for Hg%. The distribution coefficient of Th(IV), the OfiY actfide studied, was 2049J just below Zr. 77
