Anion exchange separations of the elements that are extractable with tributyl phosphate. VIII (in German)
Firstly consideration is given to the previously known theoretical bases of the ion exchange processes, in particular in organic and water-organic media, whereby such effects that are important to a selective adsorption behavior of the exchanger, such as swelling, solvation, varying distribution of organic materials between resin and solvent phases, complex formation, electroselectivity, and sieve effect are discussed. In the second part of the paper it is established that in the anion exchange behavior of various elements in mixtures consisting of TBP, methyl glycol, and hydrochloric acid with employment of the strongly basic anion exchanger Dowex 1-X8, chloride form, it may come to a competition between two oppositely acting effects, namely of the ion exchanger and the extraction (KIALE-effect). Conditions may be found under which the one or other effect predominates, It is possible to draw and establish conclusions with regard to the distribution of the individual components between resin and solvent agent phase from the adsorption behavior of uranium in mixtures consisting of tributyl phosphate, methylglycol, and hydrochloric acid and an inert diluent, namely that water and methyl alcohol accumulate chiefly in the hydrophilic polar resin phase, whereas THP, hydrochloric acid and kerosene accumulate chiefly in the nonpolar solvent phase.
