离子交换色谱法分离铀同位素与一般化学交换法一样都包括以下三个过程的循环: 1.两种铀化合物的形成; 2.在这两种化合物中间~(235)U和~(233)U 达到同位素交换平衡,并实现同位素的不等机率分配; 3.达到同位素交换平衡的两种铀化合物的两相分离。离子交换色谱法分离铀同位素与一般化学交换法不同之处仅在于两相分离过程是在一种特殊的离子交换色谱体系中进行的。这种色谱柱上的一个塔板相当于一个分离单级。由此可见,离子交换色谱法分离铀同位素仅是化学交换法的一种特殊类型。因此,本文在介绍离子交换法时,常常涉及到一般化学交换法的问题。
The separation of uranium isotopes by ion exchange chromatography involves the same three cycles as the general chemical exchange method: 1. The formation of two uranium compounds; 2. Between the two compounds, 235 U and 233 U, To achieve isotopic exchange equilibrium, and to achieve unequal distribution of isotopes; 3. Two-phase separation of two uranium compounds to achieve isotopic exchange equilibrium. Ion exchange chromatography uranium isotope separation and general chemical exchange method difference is that the two-phase separation process is carried out in a special ion exchange chromatography system. A tray on this column corresponds to a single stage of separation. Thus, the ion exchange chromatography uranium isotope separation is only a special type of chemical exchange method. Therefore, this article introduces the ion exchange method, often involves the general chemical exchange method.
