微波消解-ICP-AES法测定镁质耐火材料中次量元素

摘要

A sensitive method was developed for the determination of secondary elements in magnesite refractories by ICP with advanced microwave digestion .Under optimized conditions ,the RSD was 0 .6%-4 .8% .T he method is simple and rapid ,the date is accurate and credible.%采用微波消解技术进行样品前处理，建立了电感耦合等离子体原子发射光谱法同时测定镁质耐火材料中次量元素的分析方法。通过大量条件试验，确定了测定的最佳条件。对标样和样品进行测定，结果表明，该方法简便、快速，数据准确、可靠。
