采用两种方法实验研究了共存H/sub 2/O（同位素沼泽效应）对分子筛吸附氚化水蒸气的影响。 One was by breakthrough experiment.结果发现H/sub 2/O-HTO二组分Langmuir型吸附等温线可以很好地解释HTO穿透曲线。另一种方法是使用可分割的柱，研究 HTO 在比入口处浓度低得多的情况下的行为以及氚化水在吸附剂上的轴向分布。发现塔出口处的氚化水蒸气浓度随着输入的H/sub 2/O 浓度的增加而降低。但去污因子改善甚微。
Effect of co-existing H/sub 2/O (isotopic swamping effect) in the adsorption of tritiated water vapor on molecular sieves was experimentally studied by two means. One was by breakthrough experiment. It was found that H/sub 2/O-HTO two components Langmuir type adsorption isotherm is satisfactory to explain the HTO breakthrough curve. The other was by using a divisible column, where behavior of HTO at much lower concentration than at the inlet and the axial distribution of tritiated water on the adsorbent were studied. Concentration of tritiated water vapor at the column outlet was found to decrease with the increase of H/sub 2/O concentration of the input. However the improvement of decontamination factor was little.
