Trichloroaniline in the air was collected with micropore filter membrane 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 0.01 mg/L. When the concentration of standard solutions is 1-10 mg/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.
空气中的三氯苯胺用微孔滤膜采集，环己烷解吸，经OV - 17、OV - 210柱分离，用GC - ECD测定。对采集滤材、解吸液及采样流量进行了选择。方法的检出限为0.01mg/L，标准溶液浓度为1～10mg/L时，相对标准偏差（RSD）为4.5%～2.3%，在0.005～30mg/L范围内呈线性关系，采样效率为98.7%～100%，采样器至少可稳定15d。该方法采样、携带准确、灵敏、快速、简便，适用于空气中三氯苯胺的测定，可用于个体检测和现场检测。
