摘　　要：提出ICP-AES法测定硅钢用高纯磷铁中铌钒钛含量。对样品称样量、溶样方式、溶样酸、光谱干扰、工作曲线制备等进行了优化处理,建立了ICP-AES法测定硅钢用高纯磷铁中铌钒钛含量。此方法应用到实际样品检测,铌钒钛相对标准偏差(RSD,n=11)分别在4.6~9.0%、2.2%~12.4%、4.1~6.3%范围内,回收率分别在99.0%~101.2%、98.3%~102.5%、99.2%~102.8%,方法操作简便,自动化程度高,满足硅钢生产使用要求。This method was applied to actual sample detection.The relative standard deviation(RSD,n=11)of niobium,vanadium and titanium were in the range of 4.6%—9.0%,2.2%—12.4%,4.1%—6.3%,respectively.The recoveries were in the range of 99.0%—101.2%,98.3%—102.5%,and 99.2%—102.8%respectively.The method was easy to operate and highly automated to meet the requirements of silicon steel production.
