本文给出了在盐酸-丙酮介质中，在0.1 ~ 3.0M酸浓度和0 ~ 95%丙酮浓度范围内，用二乙烯基苯交联的磺化聚苯乙烯Bio-Rad AG 50 W-X8对54种阳离子的交换分配系数。元素根据它们在盐酸水溶液中的系数任意排列在表中。一些可能性，这个系统的分离指出，并讨论了一些方面的洗脱行为的各种元素。盐酸丙酮混合物作为阳离子交换分离的洗脱剂的通用性通过混合物Tl（III）、In、Ga、Al、Yb; Cd、Zn、Fe（III）、Cu（II）、Co（II）、Mn（II）;和V（V），Fe（III），U（VI），Ti（IV），Ca，Ba.首次尝试通过加入可与水混合的有机溶剂，以促进氯络合物在外相中的形成，来改善过渡金属的阳离子交换分离选择性地可能是由于Kendy等人。（一）.本文系统地测定了14种元素在盐酸-丙酮介质中的阳离子交换分配系数。
Cation exchange distribution coefficients with Bio-Rad AG 50W-X8, a sulfonated polystyrene cross-linked with divinyl benzene are presented for 54 cations in hydro-chloric acid-acetone media, covering the acid concen-tration range 0.1 to 3.0 M and the acetoneconcentration range 0 to 95%. The elements are arbitrarily arranged in tables according to their coefficients in aqueous hydrochloric acid. A number of the possibilities of this system for separations are pointed out and some aspects of the elution behavior of various elements are discussed. The versatility of hydrochloric acidacetone mixtures as eluting agent for cationexchange separations is demonstrated by sequential elution of the mixtures Tl (lll), In, Ga, Al, Yb; Cd, Zn, Fe (lll), Cu (ll), Co (ll), Mn (ll); and V (V), Fe (lll), U (VI), Ti (IV), Ca, Ba.The first attempt to improve the cation exchange separation of transition metals by addition of a water mixable organic solvent with theaim to promote chloride complex formation in the externalphase selectively is probably due to Kember et al.(1). A systematic survey of cation-exchange distribu-tion coefficients for 14 elements in HCl-acetone media has
