微波消解-电感耦合等离子体发射光谱法同时测定白云石中铁铝钙镁钾钠硫

Simultaneous Determination of Fe, Al, Ca, Mg, K, Na, S in Dolomite Samples by ICP-AES with Microwave Digestion

摘要: 采用微波消解白云石样品，电感耦合等离子体发射光谱法测定其中铁、铝、钙、镁、钾、钠、硫的氧化物，对微波消解条件和等离子体发射光谱仪的工作条件进行了选择，克服了常规化学分析方法步骤繁琐、耗时长、工作量大的不足。利用所建立的方法快速分析了白云石中铁、铝、钙、镁、钾、钠、硫的含量，结果与标准值或化学法相符，10次测定的相对标准偏差（RSD）7种元素均小于1％，可以满足生产和科研的要求。
