摘　　要：目的:建立一种离子色谱检测方法,用于同时测定居住区大气中氯化物、硝酸盐、硫酸盐含量。方法:选用Ion-pac AS14分离柱,Ionpac AG 14保护柱,淋洗液为Na2CO3/NaHCO3,浓度分别为3.5 mmol/L和1.0 mmol/L。流速1.0 ml/min。结果:在2 mg/L～100 mg/L浓度范围内,各待测物的线性关系良好。结论:该方法简便、灵敏。一次进样10 min内,全部分离完全,可满足国家居住区中环境卫生标准。Objective：To establish an analytical method for simultaneous determination of chloride,nitrate and sulfate in the residential air by ion chromatography.Methods： The chromatography separation was performed on an IonpacAS14 analytical column and an IonpacAG14 guard column with the eluent containing 3.5 mmol/L Na2CO3 and 1.0 mmol/L NaHCO3.The flow rate was 1.0 ml/min.Results： The linear concentration range was 2 mg/L^100 mg/L with a good correlation coefficient for each sample.Conclusion： The method is convenient with high sensitivity.It can completely separate samples only in 10 minutes which can satisfy the national residential air health standard.
