| 摘 要： | 本方法用于测定霞石中的钾、钠，主要通过在溶样时加入氢氟酸除去二氧化硅，调整溶液中钾、钠的含量，消除互相之间的干扰，加入氯化铯消除电离因素的干扰，提高了分析结果的准确性和重现性，使测定结果更接近化学分析值。回收率为99．2％-101．6％。

| Abstract: | Analysis of K and Na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove SiO 2,adjusting the ratio of K and Na in the solution to reduce the mutual interference of the two elements,and adding cesium chloride to eliminate ionization interference.The results are satisfictary and comparable to those from chemical analysis with 99.2%-101.6% of recovery. |
