【 摘 要 】

References(9)Cited-By(1)The separations of pairs of light rare-earth metal ions [La(III), Ce(III), Pr(III), Nd(III), and Sm(III)] were achieved by chromatography using glass beads coated with polyacryloylacetone as the stationary phase. Favorable resolutions were obtained by stepwise decrease in pH of the eluent (HCl). Better resolution was attained with an increase in duration of the stepwise decrease in pH. Even with pairs of neighboring elements, a fairly good separation was achieved.
