摘要
探讨了火焰原子发射光谱法测定矿石中钾和钠时的分析性能。方法确定了测定钾和钠的最佳实验条件:乙炔-空气比为2.0∶13.0;观测高度为3 cm。在最佳的实验条件下,钾和钠的检出限分别为0.01μg/mL和0.06μg/mL,回收率分别为98.7%～101.1%和98.9%～101.7%;相对标准偏差均小于3%。该法操作简便易行,具有很高的实用价值。
The analytical performances by the flame atomic emission spectrometric determination of potassium and sodium in the ores is discussed.The determination of potassium and sodium in the determination of the optimum experimental conditions are acetylene air ratio 2.0∶ 13.0;observation of height 3 cm.At the optimum experimental conditions,potassium and sodium in the limits of detection are 0.01 μg / mL and 0.06 μg / mL.Recoveries were 98.7% ～101.1% and 98.9% ～101.7%.The relative standard deviation is less than 3%.The method is simple and easy,it has very high practical value.
