本文研究了用新研制的叔吡啶型阴离子交换树脂包埋硅球分离三价锕系元素和镧系元素。以甲醇-盐酸溶液为流出液，用该树脂填充柱进行了色谱洗脱实验。从镧系元素的洗脱谱带中可以很好地洗脱出锕系元素。锕系元素和镧系元素根据其原子序数的相反顺序洗脱。
The separation of trivalent actinides and lanthanides was studied by using newly developed tertiary pyridine-type anion-exchange resin embedded in silica beads. Chromatographic elution experiments were carried out by using a packed column of the new resin and methanol-hydrochloric acid solution as an effluent. We confirmed that the actinides were eluted well from the elution bands of lanthanides. Actinides and lanthanides were eluted according to the reverse order of their atomic number.
