本文用平衡法测定铷、铯在稀硝酸或稀硝酸-甲醇(或正丁醇)与华东化工学院阳-42号树脂间的分配系数,比较用硝酸及硝酸-醇作淋洗液分离铷、铯的效果,并确定0.47M硝酸是较好的淋洗液.
In this paper, the partition coefficient of rubidium and cesium between dilute nitric acid or dilute nitric acid-methanol (or n-butanol) and Huadong Chemical Engineering Institute-Yang-42 resin was determined by the equilibrium method. Rubidium was separated by using nitric acid and nitric acid- The effect of cesium, and to determine 0.47M nitric acid is a better eluent.
