摘　　要：建立离子色谱法测定废气样品中氯化氢的分析方法。采用ICS-3000型离子色谱仪,色谱柱为AS1 8,以23mmol/L氢氧化钾溶液为淋洗液,流速为1.0mL/min;以23mmol/L氢氧化钾溶液作为废气样品的吸收液,测定污染源中的氯化氢废气。结果该方法的线性范围为0.1～1 0mg/L,r=1.0000,检出限为0.01 mg/L,在0.1、1、10mg/L浓度下进行精密度试验,RSD均小于5.0%(n=6),回收率为97%～104%。该方法操作简便、快速、准确,可避免其他阴离子及卤素和含卤酸盐离子的干扰。用离子色谱法测定污染源废气中的氮化氢是较为理想的检测方法。A novel method for the determination of hydrogen chloride in waste gas of pollution source by ion chromatography was developed,by using KOH as the elution and absorption solution.The result showed that the detection limit was 0.01mg/L;recoveries were 97%～104%;the RSDs were below 5.0%（n=6）;the linear range was 0.1～10.0mg/L .The method is sensitive,rapid and effective.
