| 摘 要： | 以保留时间定性、峰面积外标法定量,建立了离子色谱同时测定大气降水中F–,Cl–,NO2–,NO3–,SO42–5种阴离子的分析方法。结果表明,5种阴离子标准曲线线性相关系数均大于0.999 8,检出限(3s/k)在0.000 3~0.006 6 mg/L之间。F–,Cl–,NO2–,NO3–,SO42–测定结果的相对标准偏差(n=10)分别为1.70%,2.46%,9.30%,0.73%,0.67%。用该方法对水样进行测定并进行加标回收试验,5种阴离子加标回收率在91.2%~102.7%之间。该方法灵敏度高,简便、快速,能满足大气降水中阴离子分析的要求。

| Abstract: | The method for the determination of F-,Cl-,NO2-,NO3-,SO42- anions in rainwater samples by ion chromatography was established. The correlation coefficient of the linear equation was more than 0.999 8 for five anions and the detection limits （3s/k） were 0.000 3-0.006 6 mg/L. The relative standard deviations （n=10） of F-,Cl-,NO2-,NO3-, SO42-detection results were 1.70 %,2.46%,9.30%,0.73%,0.67%respectively. The method was applied to determine the five anions in rainwater sample,and the standard recoveries were in the range of 91.2%-102.7%. The method is sensitivity, simple,rapid,and it can meet the analysis demound of anions in rainwater. |
