摘　　要：该研究建立了活性碳管吸附-甲酸溶剂解析-气相色谱法测定环境空气和废气中乙酸的方法,当采样量为30L时,方法检出限为:0.015 mg/m3,加标回收率为90.3～92.6%,相对标准偏差为0.94～1.25%。方法简单、灵敏度高、分离度好、干扰少、检出限低。Acetic acid in ambient air and exhaust gas was determined by Gas chromatography in this study.Acetic acid was firstly adsorbed in activated carbon tubes and then desorbed with formic acid.With sampling volume 30 liters,the detection limit for acetic acid were 0.015 mg / m^3.The recoveries with standard addition ranged from 90.3% to 92.6%.Relative standard deviation（RSD） ranged from 0.94% to 1.25%.This method was simple and accurate,and had a high resolution and low dection limit.
