本文发现一种含有Mn~(2+)的硫酸流洗剂,可使UO_2~2和U(Ⅳ)的扩散常数分别增大20倍和400倍,从而显著地提高了UO_2~(2+)和U(Ⅳ)的阳离子色谱效率;并论证了Mn~(2+)离子的作用机理。
In this paper, we found that a sulfuric acid flux containing Mn 2+ can increase the diffusion constants of UO_2 ~ 2 and U (Ⅳ) by 20 times and 400 times, respectively, And U (Ⅳ). The mechanism of action of Mn 2+ ion was also demonstrated.
