摘　　要：目的建立测定空气中氨的更为灵敏、安全、快速的检测方法。方法以装有酸性溶液的多孔玻板吸收管采样,用离子色谱法测定空气中的氨。结果该方法的加标回收率为97.6%～99.8%,RSD为1.08%～2.93%,检出限0.05μg/ml,测定范围为0.50～4.00μg/ml。该法与纳氏试剂分光光度法的测定结果差异无统计学意义(P>0.05)。结论该方法操作简便、快速、灵敏度高、准确度好,可用于空气中的氨的测定。Objective To develop a sensitive, safe and quick method for determination of ammonia in the air. Methods The air samples collected with multi-hole absorbing tubes were determined by ion chromatography after sampling. Results The recovery rates, precision （relative standard deviation） and detection limit were 97.6%-99.8%, 1.08%-2.93% and 0.05 μg/ml, respectively. There was no significant difference between this method and chemical method. Conclusion The method is simple, quick, sensitive and suitable for determination of ammonia in the air.
