铀的离子交换平衡的研究在理论上和实用上都很重要,UO_2~(++)-H~+的阳离子交换反应是最重要的交换反应之一。Bonner、walton和Hagiwara等都曾对UO_2~(++)-H~+离子交换平衡进行过研究。尽管他们用的都是Dowex-50树脂,但实验结果却互相矛盾,不但所得平衡常数的数值不同,而且随着树脂上双氧铀克当量分数的变化,树脂对UO_2~(++)的选择性的变化 The study of ion exchange equilibrium of uranium is very important both theoretically and practically. The cation exchange reaction of UO_2 ~ (++) - H ~ + is one of the most important exchange reactions. Bonner, Walton and Hagiwara et al. Have studied the ion exchange equilibrium of UO_2 ~ (++) - H ~ +. Although they all used Dowex-50 resin, the experimental results contradict each other. Not only the numerical values ​​of the equilibrium constants obtained are different, but also the choice of UO_2 ~ (++) by the resin as the uranyl equivalents change. Sexual changes
