The quantitative analysis of tritiated water vapor in air was investigated by sorption into a non-volatile liquid scintillant solution sorbent of silicone oil. The activity of the beta-ray from the sorbed tritiated water vapor, 10(-7) microCi/mL in air, was directly measured with the help of the scintillator solution which also served as the sorbent. It was found that the variation of the partial vapor pressure of tritiated water in air was proportional to the sorbed amount in the liquid scintillator sorbent from the vaporized tritiated water. The relation was also expressed as a sorption isotherm equation and was compared to the Langmuir adsorption isotherm supporting the suggested adsorption by solid adsorbent.
通过将空气中的氚化水蒸气吸附到硅油这种非挥发性液体闪烁体溶液吸附剂中，对空气中的氚化水蒸气进行了定量分析。借助同时作为吸附剂的闪烁体溶液，直接测量了吸附的氚化水蒸气中β射线的活度，该活度在空气中为10(-7)微居里/毫升。研究发现，空气中氚化水的分压变化与从汽化的氚化水中吸附到液体闪烁体吸附剂中的量成正比。该关系也用吸附等温线方程表示，并与支持固体吸附剂吸附的朗缪尔吸附等温线进行了比较。
