摘　　要：针对高锡渣料中锡对铟测定的干扰,以硝酸-硫酸-氢溴酸溶解样品,借助乙酸乙酯萃取分离,建立一种消除锡的铟分析方法。实验结果表明,该方法的相对标准偏差为0.796%,回收率为99.4%~102.8%,能够取得满意的结果。In view of the interference of tin in high tin slag to the determination of indium,an analytical method for eliminating tin was established by dissolving the sample with nitric acid sulfuric acid hydrobromic acid and extracting and separating with ethyl acetate.The experimental results show that the relative standard deviation of this method is 0.796%,the recovery is 99.4%~102.8%,and satisfactory results can be obtained.
