摘　　要：采用原子发射光谱法和电感耦合等离子体一质谱法对硫酸生产用含铯催化剂的常量氧化铯进行了对比分析。试验结果表明：2种测定方法的加标回收率为99．2％～104．8％，得到的氧化铯测定结果准确、可靠；方法的准确度和精密度能够满足硫酸生产用含铯催化剂中氧化铯测定的需要。The constant of cesium oxide in cesium-containing catalyst used for sulphuric acid production was compared and analyzed by AES and ICP-MS methods. The results showed that the recoveries of the two measuring methods were 99.2%-104.8% with accurate and reliable data. The accuracy and precision of both methods met the requirements for cesium oxide detection in the cesium-containing catalyst used for sulphuric acid production.
