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 content of selenium in some environment and plant samples was determined by conventional neutron activation analysis, γ-γ coincidence spectrometry and cyclic neutron activation analysis, and the applicable range of the above nuclear analysis method was discussed. Dispersive hydrogen flame atomic fluorescence spectrometry were compared. The loss of selenium volatility has also been studied.
