| 摘 要： | 用盐酸-氢氟酸-硝酸微波消解对样品进行前处理,电感耦合等离子体发射光谱法测定岩石和矿物中的钼,选择202.03 nm为样品分析谱线,优化了微波消解的实验条件,可消解多个样品,减少了碱熔分解样品方法引入的基体干扰,避免了极谱法中汞对人体的伤害。用不同类型国家一级标准物质分析验证,测定结果与标准值吻合。方法精密度(RSD,n=8)小于2.0%,加标回收率为96.4%~101.3%,方法检出限为0.000 5%。该方法适用于岩石和矿物中钼的测定,制样速度快,操作简便安全,样品重现性好,能满足简单、快速、批量分析的要求。 |

| Abstract: | Molybdenum in rock and mineral samples were dissolved by HCl-HF-HNO3 with micro-wave digestion,and measured by inductively coupled plasma-atomic emission spectrometry(ICP-AES).The experimental conditions for microwave digestion were optimized,for example,select 202.03 nm spectral line for sample analysis,run multi samples simultaneously and reduce the matrix interference by alkali fusion.The damages to the human body were avoided as not using mercury compared with method of polarography.The reliability of t... |
