摘要
用HDEHP并以正庚烷为稀释剂从存在大量的Ag(Ⅰ)和Cu(Ⅱ)的硝酸溶液中萃取In(Ⅲ)。研究了In(Ⅲ)在两相之间的分配比与酸度、HDEHP浓度及In(Ⅲ)含量的关系。用不同浓度的盐酸从有机相中反萃取In(Ⅲ),并测量了In(Ⅲ)的回收率。从回旋加速器内靶装置上,用α粒子辐照的镀银靶物质中,分离出高纯度、无载体的 ̄(111)In,并制成了 ̄(111)InCl_3注射液。
The distribution ratioes of In(Ⅲ)between organic and aqueous phasas in the solventextraction of In(Ⅲ)with HDEHP are determined. The distribution ratioes of In(Ⅲ)decreases as theacidity increases, increases as the HDEHP concentration increases and decreases as the In(Ⅲ)concentrations increases,The In(Ⅲ)in the organic phase can be back extracted with HCl solution ofvarious concentrations;when the In(Ⅲ)in the organic phase is back extracted with 1 mol/Lhydrochloric acid solution,the back extraction yield is in the range from 95%±1% to 96.05%±0.95%.The α-particale energy is selected in the range of 24 ~ 25MeV. The cumulative charge quantitiesof α-paricle beams bombarding the electroplating silver target are in the range of 1500μA·h~200μA·h.The radiochemical separation of the  ̄(111)In is carried out with the HDEHP solvent extraction fromthe irradiated electroplating silver target. The radioactivity yield of  ̄(111)In is 4.4×10 ̄6Bq·μA ̄(-1)·h ̄(-1).The impurity elements contained in lmL of  ̄(111)InCl_3 injection are Cu≤0.04μg Fe≤0.15μgand Ag≤2μg.
