在浓缩铀同位索的阳离子交换法中,UC_2~(2+)在离子交换树脂中的传质问题具有特别重要的意义.但迄今未见有详细的报道.本文对阳离子交换树脂—HCl溶液体系中的UO_2~(2+)—H~+正、逆交换,特别对~(235)UO_2~(2+)—~(238)UO_2~(2+)交换动力学及机制作了研究和探讨.
In the cation exchange of enriched uranium isotopes, the problem of mass transfer of UC_2 ~ (2+) ions in ion exchange resins is of particular importance, but so far no detailed reports have been reported.In this paper, the cation exchange resin-HCl solution system In particular, the exchange kinetics and mechanism of ~ (235) UO_2 ~ (2 +) - ~ (238) UO_2 ~ (2+) have been studied and discussed. .
