| 摘 要： | 本文研究了一种净化空气中氚的新方法，我们用四水合磷酸轴酰氢（Hup)作消氚剂，在外加直流电场的作用下，直接消除潮湿空气中的氚，用不同面积的消氚圆片，在静态，常温，常压下，外加4－7伏直流电场，50小时左右，可使2．2升含氚空气中氚的净化率超过90％，空气中氚含量为0．2－10ppm，含水量为3000－12000ppm，我们用液闪测量了消氚后圆片中氚的含量，其结果与用电离室所测的结果一致。

| Abstract: | A new rnethod for rernoving tritium gas from air was studied.Using hydrogen uranyl phosphate(HUP)as getter,we di- rectly gettered the tritium gas from the moist air ,using disks of gettering ritium electrcales of vdrying sizes,at room-temperature and or- dinary pressure,we gettered the tritum gas contained in 2.2 L air by the action of 4-7 de electric field,within 50 hr or so,efficiency of the gettering tritium gas for the air containing tritium 0.2-10ppm and water vapour 3000-12000ppm,was over 90%,Operating liquid scintillation counter,we measured the tritium in the disks after gettering,the results agreed with ones reducing tritium in the ionization chamber. |
