采用离子色谱法测定降水中的阴阳离子。F–，Cl–，NO2–，NO3–，SO42–，PO43–6种阴离子的检出限在0.002～0.015 mg／L之间，Na+，NH4+，K+，Mg2+，Ca2+5种阳离子的检出限在0.010～0.025 mg／L之间。阴离子加标回收率在88.4%～109%之间，相对标准偏差小于5%；阳离子加标回收率在85.0%～112%之间，相对标准偏差小于7%。用离子色谱法测定降水中的阴阳离子，操作简单、快捷，灵敏度高。
採用離子色譜法測定降水中的陰暘離子。F–，Cl–，NO2–，NO3–，SO42–，PO43–6種陰離子的檢齣限在0.002～0.015 mg／L之間，Na+，NH4+，K+，Mg2+，Ca2+5種暘離子的檢齣限在0.010～0.025 mg／L之間。陰離子加標迴收率在88.4%～109%之間，相對標準偏差小于5%；暘離子加標迴收率在85.0%～112%之間，相對標準偏差小于7%。用離子色譜法測定降水中的陰暘離子，操作簡單、快捷，靈敏度高。

A method for simuhaneous determination of anions and cations in precipitation by dual channel capillary ion chromatography was established. Determination limits of the method were 0.002–0.015 mg/L for F–,Cl–,NO2–,NO3–, SO42–,PO43– and 0.010–0.025 mg/L for Na+,NH4+,K+,Mg2+,Ca2+. Recoveries were from 88.4% to 109% for anions and from 85.0% to 112% for cations. The RSDs of determination were lower than 5% for anions and 7% for cations. The method had high sensitivity,speediness and exactness.
