In this work, we compare methods for the sequential determination of U and the transuranium elements Np, Pu, Am, and Cm. The chemical yield, the time spent in the analysis, the amount of secondary waste, and the costs of each method are the aspects of interest. Two methods were compared: extraction chromatography (EC) and ion exchange plus extraction chromatography (IE + EC). The chemical yields of (EC) and (IE + EC) were similar for all radionuclides. The (EC) method is the more effective with respect to time of analysis, the amount of secondary waste and costs.

连续分析活性炭滤床废物中锕系元素同位素的放射性分析方法

在这项工作中，我们比较了连续测定 U 和超铀元素 Np、Pu、Am 和 Cm 的方法。化学产量、分析所花费的时间、二次废物的数量以及每种方法的成本都是关注的方面。比较了两种方法：萃取色谱 (EC) 和离子交换加萃取色谱 (IE + EC)。所有放射性核素的 (EC) 和 (IE + EC) 的化学产率相似。(EC) 方法在分析时间、二次废物量和成本方面更有效。
