7203对铀的萃职能力较差。萃取纯铀溶液时,其分配比最大为26。此时的单级萃取率仅86.8％,饱和容量(浓度为0.1M 7203)为3.6克/升。 7203对钼具有较高的萃取能力,分配比可达253.8,单级萃取率为98.8％。但是,这些工艺指标仍不及三脂肪胺。在同样条件下,脂肪胺萃取钼时,其分配比可达556。另外,7203对钼的选择性也不及三脂肪胺,但如果用TBP作添加剂,当其用
7203 less capable of uranium extraction. Extraction uranium solution, the distribution ratio of up to 26. The single-stage extraction rate at this time was only 86.8% and the saturation capacity (0.1 M 7203) was 3.6 g / L. 7203 has higher extraction ability to molybdenum, the distribution ratio can reach 253.8 and the single-stage extraction rate is 98.8%. However, these technical indicators are still less than the three fatty amine. Under the same conditions, fatty amine extraction of molybdenum, the distribution ratio up to 556. In addition, the selectivity of 7203 to molybdenum is less than that of tri-fatty amines, but if TBP is used as an additive,
