降低贫有机相中铀质量浓度的研究

STUDY ON DECREASE OF URANIUM CONCENTRATION IN LEAN ORGANIC PHASE

纯化铀工序的反萃取结晶作业中 ,贫有机相中 ρ(U)不断增高 ,甚至达到 2 g/ L 以上。严重影响回收率和生产能力 ,威胁产品质量 ,增加了试剂消耗。通过实验研究 ,找到了用 Na OH溶液处理贫有机相的办法。

Uranium concentration increases constantly to 2 g/L in process of stripping crystalizing in uranium purification, which can deeply affect direct recovery and production ability, threaten product quality and increase reagent consumption. The problem can be solved with NaOH solution.
