摘要
作者继续进行了一系列关于在液-液系统中使用三正辛胺作为有机相的主要成分，通过化学交换分离硼同位素的研究。通过对矩形级联分离硼同位素的操作进行实验建模，得出了分离度 K = 1.0961 ± 0.0016，在产物萃取模式下，分离周期长达 30 小时。所获得的数据用于确定在最大分离度 Km = 1.109 下进行产品萃取时，达到稳定状态所需的浓缩时间 τ = 19-21 h。在不进行产品萃取的模式下，达到稳定状态所需的时间为 τ = 130-160 小时，相当于最大分离度 Km = 1.131。
Experimental Modeling of Boron-10 Isotope Enrichment during Chemical Exchange in a Liquid–Liquid System
The authors continue their set of studies on the separation of boron isotopes by means of chemical exchange in liquid–liquid systems using tri-n-octylamine as the main component of the organic phase. Degree of separation K = 1.0961 ± 0.0016 was obtained using experimental modeling of the operation of a rectangular cascade for separating boron isotopes in a 30-h long period of separation in the mode of product extraction. The obtained data are used to determine period τ = 19–21 h of concentration needed to reach a steady state when operating with product extraction at maximum degree of separation Km = 1.109. The time needed to reach a steady state is τ = 130–160 h when operating in the mode without product extraction, which corresponds to maximum degree of separation Km = 1.131.
