| 摘 要： | 本文介绍了所建立的环境样品中的自由氚和组织结合氚的分别采样装置和方法。对于样品中的自由氚,用低真空干燥回收法,回收率可达98％;对于样品中的组织结合氚,用连续加样催化氧化冷凝收集法,回收率为93％。两法都能一次收集足够制两个并行测量样的水量。

| Abstract: | This paper described the equipments and methods of collection of free-tritium and bound-tritium in environmental samples. The method of low vacuum drying with a yield of 98% was used for collecting free-tritium. A method of catalytic oxidation was used for recovering of bound-tritium with a yield about 93%. The water quantity collected per run from both equipment was large enough to prepare two parallel samples for low background liquid scintillation measurement. |
