【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。更多还原

【Abstract】 In this paper a method for the determination of Fe,Al,Ca,Mg,K,Na and S in dolomite samples by ICP-AES with microwave sample digestion was established.The conditions for sample digestion procedure and(instrumental) measurement were optimized.The method has been 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.更多还原
