摘　　要：在使用火焰光度计测试山东某长石矿时,采用传统方法,出现氧化钠结果偏差的问题。本文以钾长石、钠长石标准物质为参考,对矿石中氧化钾、氧化钠含量高低对互相之间的影响进行研究。试验结果表明,氧化钾对氧化钠的测定干扰严重,氧化钠对氧化钾的测定干扰较小,并探讨了消除相互干扰的方法。用所改进的方法进行了某矿区800余件样品测试,分析结果理想,对准确测定长石中氧化钾、氧化钠含量具有一定指导意义。When flame photometer is used to test a feldspar ore in Shandong,the deviation of sodium oxide results occurs when traditional method is used.In this paper,potassium feldspar and albite are used as reference to study the influence of content of potassium oxide and sodium oxide on each other.The experimental results show that the interference of potassium oxide to the determination of sodium oxide is serious,the interference of sodium oxide to the determination of potassium oxide is small,and the method of eliminating mutual interference is discussed.More than 800 samples from a mining area were tested by the improved method,and the results are satisfactory,which has certain guiding significance for the accurate determination of potassium oxide and sodium oxide in feldspar.
