摘要
研究了测定核级银铟镉合金中Ａｇ、Ｉｎ、Ｃｄ 的连续滴定法。以电位滴定法测定Ａｇ；在ｐＨ２．５ 以ＥＤＴＡ滴定Ｉｎ；在ｐＨ≥５．５ 以ＥＤＴＡ滴定Ｃｄ，当ｎ＝ １１ 时，其ＲＳＤ分别为：Ａｇ ０．１１％ 、Ｉｎ ０．５２％ 、Ｃｄ １．１％ ，合成试样分析回收率分别为：Ａｇ ９９．８％ ～１００．１％ 、Ｉｎ ９９．６％ ～１００．３％ 、Ｃｏ ９７．６％ ～１０１．３％ ，测定９２ 个合金试样，其Ａｇ，Ｉｎ，Ｃｄ 合量范围为：９９．７８％ ～１００．１４％ 。
This paper studied the method of determination for Ag,In and Cd in AgInCd alloys of nuclear gradc by successive titration analysis.Ag was determined by potentiometric titration method,In was determined by complexometric titration with EDTA at pH2 5 and Cd was determined by complexometric titration with EDTA at pH5 5 The relative standard deviations are:Ag 0 14%,In 0 52%,Cd 1 4%,respectively( n =11),the recoveries of synthetic samples were Ag 99 8%～100 1%,In 99 6%～100 3%,Cd 97 65%～101 3%,respectively( n =11)
