中文摘要:

      采用静态法对质量分数分别为0.7%、4.0%(无杂质)和4.0%(含杂质)的硼酸/水溶液的汽液相平衡性质进行了实验研究,测量的温度为343.15~393.15 K。利用实验数据,计算得到了硼酸在溶液中的相对挥发度。所得结论对于核电站硼回收系统的高效硼酸分离塔的优化设计具有重要的价值。

英文摘要:

      The vapor-liquid equilibrium of boric acid aqueous solution was investigated under different temperatures ranging from 343.15 to 393.15 K and the 10B concentrations of 0.7 wt%, 4 wt% (without impurity) and 4 wt% (impurity), respectively. The relative volatility of 10B in the mixtures was also calculated based on the experimental data.
