摘　　要：选用盐酸、硝酸、氢氟酸和高氯酸的4种混合酸,采用微波消解仪封闭溶解样品,用电感耦合等离子体光谱法(ICP-OES),可直接测定铁精粉中的K,Na,Ca,Mg,Al,P,Ti,Mn,Cu,回收率95.45%～102.54%,相对标准偏差(RSD)﹤5%,该方法使用试剂少,成本低,检出限低,灵敏度高,具有较好的准确度和精密度,方法简单、快速,污染少,结果较为满意。The powdered iron was dissolved by microwave digestion using HC1-HNO3_HF- HC104 as mixed digestion liquid, then ICP-OES was applied to directly detect the content of K,Na,Ca,Mg,A1,P, Ti,Mn and Cu in powdered iron. The recovery was 95.45%~ 102.54%, the variation coefficient RSD was less 5%. The results show that the method has lower cost, low detection limit, high sensitivity, great accuracy and precision.
