摘要
采用草酸处理过的玻璃纤维滤膜来采集大气中的氨及低级脂肪胺，超声浸取后，注入离子色谱仪分析。用本方法测定大气中的氨及低级脂肪胺，当采样体积为２．４ｍ３时，其中氨与三甲胺的最低检出限分别为２×１０－４ｍｇ／ｍ３和２×１０－３ｍｇ／ｍ３。
? Ammonia and lower aliphatic amine in the air was collected by glass fiber filter film, which was pretreated by oxalic acid, and then analyzed by ion chromatography after the sample being extracted by ultrasonic process. The minimum detection li-mit of ammonia and trimetylmine was 2×10-4mg/m3 and 2×10-3mg/m3 respectively.
