| 摘 要： | 文章研究了用离子色谱法直接测定降水中阴离子的色谱条件、线性范围。实验研究表明,Fˉ、Clˉ、NO3ˉ、SO42ˉ方法的最小检出限分别为:0.006、0.012、0.020、0.037 mg/L;相对标准偏差均在10%以下,加标回收率为95.9%～102.4%。用离子色谱法直接测定大气降水中的阴离子,操作简单、快捷,具有可靠的准确度和良好的精密度,且灵敏度高,实验结果令人满意。

| Abstract: | The chromatographic condition and the linear range of anions in rainfall are studied by direct determination with ion chromatography in the paper.The results showed the limits of identification of these anions were 0.006,0.012,0.020,0.037 mg/L for Fˉ,Clˉ,NO3ˉ,SO4^2ˉrespectively,and all the relative standard deviation were below 10 %.The recovery rate was 95.9 %～102.4 %.This method was simple and rapid,and also had reliable accuracy and good precision.The results were satisfactory. |
