    Abstract:
    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.
