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 K_m = 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 K_m = 1.131.
