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。
In this paper a method for the determination of Fe, Al, ICP-AES with microwave sample digestion was established. The instrumental measurement were optimized. The method has been Ca, Mg, K, Na and S in do conditions for sample digesti lomite samples by on procedure and applied to the determination of Fe, Al, Ca, Mg, K, Na and S in dolomite samples. The results are in agreement with certified values with precision of less than 1% RSD （n = 10） for all these 7 elements.
