Coefficients, distribution—See

In contrast to the investigations with calcium where Ca, which is not the preferable calcium isotope for application purposes, is enriched in the chloroform phase (see Chap. 4.2.2), Li which is of importance for the production of tritium is enriched in that phase. Certainly, corresponding to the disadvantageous distribution coefficient (see Table 10) a small amount of enriched Li is only obtainable within one equilibrium stage. Therefore, a cascade experiment as described in Chap. 2.5.2 must be applied. 

Preference or affinity is measured by a selectivity or distribution coefficient (see section 3.5). The reduction of this selectivity with increased adsorption is most pro-... 

Langmuir coefficient [Fig. 10-1 and Eq. (6-9)] sample adsorption distribution coefficient (see previous chapters)... 

D is the equilibrium distribution coefficient (see Equations 13.2, 13.5, and 13.6) kisa rate constant... 

This parameter allows for the description of measured distribution coefficients, see... 

Pj (g/cm ) is the bulk density of the packed bed, 0 (no units) is the porosity, and (cmVg) is the distribution coefficient. See Zheng and Beimett (1995) for a derivation of this equation. It is related to the (mol/g-soHd/ mol/kg-water) derived in Chapter 6 by a units transformation involving the molecular weight of the adsorbing species and the density of water. Because Kspecific surface area of the solid. 

These values illustrate the effective competition of macro U(VI) over trace Pu(IV) in the simultaneous extraction of these species, resulting in a large reduction of the Pu distribution coefficients (see Fig. 5).
