【摘要】 采用火焰原子吸收光谱法测定高纯氯化铷中钠和钾的含量。加入氯化铯作为抑制剂,消除了钠、钾的电离干扰。钠、钾测定结果的相对标准偏差分别为 17. 4%、8. 6%,回收率分别为 92% ~103%、94% ~105%。更多还原

【Abstract】 The contents of sodium and potassium in high purity rubidium chloride were determined by flame atomic absorption spectrometry. Cesium chloride was added as the ionization buffer to eliminate the ionization interference of sodium and potassium. The relative standard deviation was 17.4% for sodium and 8.6% for potassium. The recoveries of Na and K were 92%~103%, 94%~105% respectively.更多还原
