环境和植物样品中微量元素硒的核分析方法

Nuclear analytical methods for trace element Se in environmental and botanic samples

本工作利用常规中子活化分析法、γ-γ符合谱测量法和循环中子活化分析法,测定了一些环境和植物样品中的硒含量,讨论了上述核分析方法的适用范围,并与非色散氢火焰原子荧光光谱法作了比较。对硒的挥发性损失也作了研究。

In this work the conventional neutron activation analysis, γ-γ coincidence spectrometry and cyclic neutron activation analysis were used to determine selenium contents in some environmental and botanic samples. The applicability of these methods was discussed and the comparison with the non-dispersive hydrogen flame atomic fluorescent spectrometry was made. The volatile loss of selenium at high temperature was also studied.
