摘要
采用高氯酸-盐酸-硝酸-氢氟酸消解样品,ICP-AES法测定水系沉积物样品中35种常量、次量和微量元素,筛选不同溶矿方法和仪器参数条件,测定的相对标准偏差低于7.50%,经国家一级水系沉积物标准物质分析验证,结果与标准值吻合。
The quantitative analyses of 35 major, minor and trace elements in stream sediment were performed using ICP-AES with mixed acid pre-treated samples. The detection parameters for different ore melting methods and instrument operations were also optimized. The RSD was less than 7.50%, which exactly matches the national standard value.
