在核医学上~(111)In是一种由加速器生产的非常重要的同位素。它的主要用途为软组织肿瘤定位、绘制脑图、延脑池扫描、淋巴系统的肿瘤定位等。它既可作注射液,又可作标记化合物。本文研究了In(Ⅲ)在两相中的分配比与酸度的关系,与二-(2-乙基己基)磷酸(简称D2EHPA)浓度的关系,与In(Ⅲ)含量的关系,用不同酸度的HCl溶液从D2EHPA有机相中反萃取In(Ⅲ),在1mol/1HCl溶液中从有机相中反萃取In(Ⅲ)得到的回收率平均值为90.6±2.4％。
In nuclear medicine ~ (111) In is a very important isotope produced by the accelerator. Its main purpose is the localization of soft tissue tumors, brain mapping, extension of the brain pool scan, lymphatic system tumor location. It can be used as injection, but also for marking compounds. In this paper, the relationship between the distribution ratio of In (Ⅲ) and acidity, the relationship with the concentration of di (2-ethylhexyl) phosphoric acid (D2EHPA) and the content of In (Ⅲ) HCl solution from the D2EHPA organic phase. The average recovery of In (Ⅲ) from the organic phase in 1mol / 1HCl solution was 90.6 ± 2.4%.
