本文提出可以综合利用微量量热滴定法、萃取平衡法、Karl Fischer法研究协萃反应机理。各方法间可相互补充阐明机理。其中结合计算机程序的量热滴定法能在极短期间得到一系列热力学函数,便于筛选萃取剂,探索分离条件,对研究锕系、镧系全系列元素及裂变产物的萃取行为,尤为快速、简便。
In this paper, it is proposed that the synergistic reaction mechanism can be studied comprehensively by microcalorimetry, extraction equilibrium method and Karl Fischer method. The methods can complement each other to clarify the mechanism. Among them, the calorimetric titration method combined with computer program can obtain a series of thermodynamic functions in a very short period of time, which is convenient for screening extractants and exploring the separation conditions. It is very fast and easy to study the extraction behavior of actinides, lanthanide series elements and fission products .
