用微孔滤膜采集空气中三氯苯胺，以环己烷解吸，经OV-17和OV-210混合色谱柱分离，电子捕获检测器检测测定。对采集滤料、洗脱溶剂、采样流量进行了优选。方法的检出限为0.01mg/L,当标准溶液浓度为1～10mg/L时，相对标准偏差为4.5%～2.3%，线性范围为0.005～30mg/L。采样效率为98.7%～100%，样品在采样管中可稳定15天以上。通过现场试验和验证试验证明该方法准确、灵敏、快速、简便，采样和运输携带方便，适用于空气中三氯苯胺的定点监测和个体监测。由现场收集的样品各项指标均符合“车间空气中有毒物质监测研究规范”和劳动卫生监测的要求。

Trichloroaniline in the air was collected with micropore filtermembrane and desorbed with cyclohexane, separated with a column OV-17,OV—210 and determined by GC—ECD.The materals for the filter of collection, solution of desorping and flow-rate of sampling were selected. The detectable limit is 0.01mg/L. When the concentration of standard solution is 1—10mg/L, the relative standard deviation (RSD) is 4.5%—2.3%. There is a linear relation within the range of 0.005—30 mg/L. The sampling efficiency is 98.7%—100%. The samplers were stable for at least 15 days. This method is proved to be accurate, sensitive, fast and simple for sampling and carrying,and it is method is suitable for the determination of trichloroaniline in air, for personal detection and detection in the fields.
