| 摘 要： | 用火焰原子吸收法测定氯化钾中氯化钠含量,采用钠的次灵敏线330.3 nm作为测定波长,扩大了标准曲线的线性浓度范围,简化了操作。通过对氯化钾样品中钠含量准确度对比检测试验、加标回收率试验、精密度试验验证,表明改进后的方法简单易行,提高了测定的速度和准确度。

| Abstract: | The sodium chloride content in potassium chloride is determined by flame atomic absorption spectrometry , the sub-sensitivity line of sodium 330 .0 nm is chosen as determination wavelength , expanding linear concentration range of standard curve , and simplifying operation . Through accuracy contrast determination test of sodium content in potassium chloride samples , recovery test of standard sample , and precision test , the verification indicates that the improved method is simple and easy to apply , and the determination speed and accuracy are improved . |
