Abstract

A single separation effect between deuterium and protium was studied experimentally under phase equilibrium conditions in a water vapor–water salt solution system at temperatures from 59 to 94°C. The vapor–liquid equilibrium was investigated by the dynamic method in a Bushmakin device. The presence of urea in water significantly increased the separation coefficient α_L–V in the given temperature range. The characteristic increase in the relative volatility coefficient of the hydrogen isotopes of water remained unchanged at lower temperatures in the presence of salts. The isotope salt effects, both negative and positive, increased with the salt concentration.

盐溶液中气液平衡时各相之间氢同位素的分布

摘要

在相平衡条件下，在水蒸气-水盐溶液系统中，温度从59到94°C，研究了氘和pro之间的单一分离效果。在Bushmakin装置中通过动态方法研究了气液平衡。在给定温度范围内，水中存在尿素会显着增加分离系数αL _–V。在盐的存在下，水的氢同位素的相对挥发性系数的特征增加在较低温度下保持不变。同位素盐的影响，无论是正面的还是负面的，都随着盐浓度的增加而增加。
