摘　　要：采用电感耦合等离子体发射光谱法同时测定工业氯化钡中钙、铁、钠、锶的含量,检测限(以质量浓度计)分别是0.02、0.02、0.01、0.2 mg/L,该测试方法的相对标准偏差≤8.69%,加标回收率为88%～112%,简单、快速、准确度高。The calcium, iron, sodium and strontium contents in industrial barium chloride were determined simultaneously by ICP-OES. The determination limit was 0.02, 0.02, 0.01 and 0.2 mg/L, respectively. This determination method was simple, rapid and accurate with RSD not above than 8.69% and the recovery of standard addition of 88% - 112%.
