本文报道了从含钼酸盐的碳酸盐溶液中选择萃取分离铀的方法。液相色谱柱中充填固定在可控制微孔玻璃球的N-B氨乙基-r-氨丙基三甲氯基硅烷,这种被用于连续的液流体系。碳酸铀酰离子〔UO_2(CO_3)_2·2H_2O〕~(2-)和UO_2(CO_3)_3~(4-)选择性地被吸附在质子化了的固定的双胺上是这种分分离的基础。在所推荐的试验条件下,对人工配制的试样,铀的回收率为96.7—113.4％,钼酸盐的回收率则为95.7—110.5％,
This paper reports the method of selective extraction of uranium from molybdate-containing carbonate solutions. The liquid column was filled with N-B aminoethyl-r-aminopropyltrimethoxysilane fixed on a controllable microporous glass sphere, which was used in a continuous flow system. Uranyl carbonate ion [UO_2 (CO_3) _2 · 2H_2O] ~ (2-) and UO_2 (CO_3) _3 ~ (4-) are selectively adsorbed on protonated immobilized bisamines basis. Under the recommended experimental conditions, the recovery rate of uranium was 96.7-113.4% and that of molybdate was 95.7-110.5% for artificial preparation samples,
