| 摘 要： | 本文揭示了钠、钾受基体元素碲干扰的现象和分析系统中酸度对钠、钾吸光度的影响,在理论上探讨了碲对钠、钾干扰的原因,利用加入盐酸和铝元素的方法分别排除碲对钾、钠的干扰,提出一个方便,实用的测定方法,回收率和RSD分别为95-102%和7.4%。

| Abstract: | The interference of Te on test of Na and K had been exposured in this experi ment. The cause of interference in testing Na and K had been studied theoretically. A easy method of Na and K had been developed. The RSD and recovery in Na and K is 7.4% and about 95-102% respectively. |
