以钯-铂合金(8at.%Pt)为功能材料，研制了一种用于氢同位素分离的新型色谱柱。它可以在274-297K的温度范围内，在短时间内将H2-D2混合物分离为H2和D2，操作步骤简单，无需引入任何替代气体。回避机制在分离中起着重要作用，置换机制和/或混合效应也可能参与其中。在适宜的操作温度、较高的载气压力和较低的流速条件下，分离效果较好。这种新的层析技术在热核聚变装置的同位素分离系统中具有潜在的应用前景。
A new type of chromatography for hydrogen isotope separation was developed employing a Pd–Pt alloy (8 at.% Pt) as functional material. It could separate a H2–D2mixture into H2and D2in the temperature range of 274–297 K in a short time with simple operation procedures without introducing any replacement gas. An elusion mechanism plays an important role in the separation, and a replacement mechanism and/or a mixing effect may also be participating. A good separation can be expected under conditions of moderate operation temperature, a high carrier gas pressure and a slow flow rate. The new chromatography has potential for application in isotope separation systems for thermonuclear fusion devices.
