摘　　要：建立了ICP-OES测定铯榴石中铯含量的方法,采用酸溶加热消解法处理铯榴石样品,对酸溶解和分析谱线的选择进行了讨论,优化了仪器工作条件。结果表明:Cs在特征波长894.347 nm基体干扰小,标准曲线拟合佳,相关线性系数R≥0.9998,检出限低,精密度好RSD(n=11)≤0.5%,加标回收率在97.4%~101.2%之间。该方法可用于铯榴石进口的准确、快速检验。In this paper,a method for determining the content of cesium in cesium garnet was established by the high-resolution inductively coupled plasma emission spectrometer.The cesium garnet sample is processed by acid-soluble heating digestion.The choice of dissolution method and analytical line are discussed,and instrument working conditions have been optimized.The test results show that Cs has low matrix interference at the characteristic wavelength of 894.347 nm,good standard curve fitting,correlation linear coefficient R≥0.9998,low detection limit,good precision RSD(n=11)≤0.5%,and the standard recovery rate is 97.4%to 101.2%.This method can be used for accurate and rapid inspection of cesium garnet imports.
