Abstract
Abstract Cation-exchange distribution coefficients with Bio-Rad AG50W-X8, a sulphonated polystyrene cross-linked with divinylbenzene are presented for 54 cations in hydrobromic acid-acetone media, ranging from 0.1 to 3.0 M acid and 0 to 95% acetone. The elements are arbitrarily arranged according to their coefficients in aqueous hydrobromic acid. Some possible separations are pointed out and aspects of the elution behaviour of various elements are discussed. The versatility of hydrobromic acid-acetone mixtures as eluting agents for cation-exchange separations are demonstrated by sequential elution of the mixtures Hg(II). Cd, In, Zn, Cu(II) and Co(II); Bi(III), Pb, Zn, Fe(III) and Mn(II); and Au(III), Cd, In, Ga, Al and Sc.
