【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.更多还原
