| 摘 要： | 本文提出了一种流动注射原子吸收光谱法测定高纯水合锑酸钠中钾的方法，优化了仪器参数，考察了几种可能的干扰成分如Ｎａ＾＋、Ｓｂ（Ｖ）、酒石酸等，并提出了消除干扰的方法。结果表明通过在样品和标准液中加入一定量的Ｎａ＾＋后，匹配二者基体可以应用标准曲线法校正，方法的精密度（ＲＳＤ）为１．５％，回收率为９８．６％。

| Abstract: | A method for determination of micro potassium in high-purity NaSb (OH)_6 by AAS was proposed, instrumental parameters was optimized, several possible interfering factors such as Na~+, Sb(V), tartaric acid and HCl were examined in detail. Experimenal results indicated that the standard calibration method can be used after matching the matrixes of sample and standard by adding certain amount of sodium. The variale coefficient was about 1.5%, recovery ranges from 95.3% to 101.3%. |
