DISTRIBUTION COEFFICIENTS AND CATION-EXCHANGE BEHAVIOUR OF ELEMENTS IN HYDROCHLORIC ACID-ETHANOL MIXTURES

Cation-exchange equilibrium distribution coefficients with Bio-Rad AG50W-X8, a sulfonated polystyrene resin, are presented for 45 elements in hydrochloric acid-ethanol media. The acid concentration range 0.1-3.0 M and the ethanol concentration range 0-95% are covered. The elements are arbitrarily arranged in tables according to their coefficients in aqueous hydrochloric acid. Possibilities for separations inherent in the system are demonstrated by elution curves for the multicomponent systems Fe(III)-U(VI)-Ca(II)-La(III); Cd(II)-Zn(II)-Fe(III)-Ca(II)-Ba(II); and In(III)-Ga(III)-Be(II)-Al(III)-Y(III). Some aspects in the elution behaviour of various elements are discussed. © 1969.
