| 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. |
