THE EXTRACTION OF In (Ⅲ) FROM NITRIC ACID SOLUTION CONTAINING LARGE AMOUNT OF Ag(Ⅰ) WITH HDEHP

  • 摘要: <正> 前言 ~(111)In是近年来很受人们注意的一种医用同位素。产生~(111)In的主要核反应有~(109)Ag(α,2n)~(111)In,~(111)Cd(p,n)~(111)In,~(111)Cd(d,2n)~(111)In。In(Ⅲ)的分离方法有HCl沉淀Ag(Ⅰ)法;阴离子交换法;甲基异丁基酮萃取法;把In(Ⅲ)转化为溴化物后,用异丙醚萃取,再用8M HCl反萃取等方法。用二(2-乙基己基)磷酸(HDEHP)萃取\n(Ⅲ)的报道尚未多见。
    Abstract: The distribution ratio of In(Ⅲ) between organic and aqueous phases in the solvent extraction of In (Ⅲ) with HDEHP is determined.The distribution ratio of In(Ⅲ) decreases as the acidity increases and increases as HDEHP concentrations increase and In(Ⅲ) concentrations decrease.In(Ⅲ) in the organic phase can be back extracted with HC1 of various concentrations. When In(Ⅲ) in the organic phases is back extracted with 1 M hydrochloric acid,the back extraction yield is 90.6±2.3%.The gamma spectrum of 111In separated from irradiated silver target is measured.
