^(201)Pb-^(201)Tl母子体系的研究

STUDY ON ^(201)Pb-^(201)TI GENERATOR

将Aftanas的方法应用于^(201)pb-^(201)Tl母子体系,得出了^(201)pb-^(201)Tl母子体系的淋洗效率与柱载带量、水合pb^(2+)离子半径等参数之间的定量关系。并通过实验验证了这一关系。本研究将^(201)Pb-^(201)Tl母子体系的淋洗效率同使用条件下pb^(2+),Tl^(3+)的物理、化学状态联系起来,探讨了淋洗机制,为提高淋洗效率的研究提供了依据。

Aftanas' method is applied to 201pb-201Tl generator and a quantitative formula relating the elution yield to the column load,the radius and the density of hydrous lead ion,etc. ,is induced in the essay. This formula is verified with experiments. This work related the elution yield to the physical and chemical states of Pb2+ and Tl3+under the working condition .investigated the elution mechanism and provided the foundation to the study on increasing elution yield.
