空气中不同形态氚取样方法

Review of Sampling Methods of Chemical Forms of Tritium in Ambient Air

空气中氚的存在形态主要是氚化水蒸气(HTO)、氚气(HT)和氚化甲烷(CH3T)。空气中的氚含量很低,测定通常采用累积取样和液闪谱仪测量相结合的方法。本文综述了空气中不同形态氚的取样方法的研究进展,对不同取样方法进行了比较分析,总结了不同取样方法存在的问题和不足,为空气中氚的取样方法研究提供参考。

There are three different chemical forms of tritium in ambient air, tritium oxide, tritium hydrogen, and tritium methane. This paper reviews the research progress of sampling method of tritium in ambient air. Different methods are discussed and compared each other. Some new idea is suggested to improve the present method for higher sampling efficiency and recovery. The information in this paper could play an important reference role for development of new high efficient different sampling methods for tritium in ambient air.
