后处理1AW样品具有化学成分复杂、比放高的特点,是后处理分析的难点之一。为了分析1AW中的微量铀、镎、钚含量,建立了一种将铀、镎、钚共吸附,顺序洗脱分离的预处理方法。方法简便、快捷,可去除绝大部分干扰基体及放射性裂变产物核素。 The post-treatment 1AW sample has the characteristics of complex chemical composition and higher specific heights, which is one of the difficulties of post-treatment analysis. In order to analyze the trace amounts of uranium, gallium and plutonium in 1AW, a pretreatment method of co-adsorption and sequential elution of uranium, plutonium and plutonium was established. The method is simple and fast, can remove most of the interference matrix and radioactive fission products nuclides.
