| Abstract: | We use pure water to Absorb the n-butyl alcohol in ambient air and exhaust gas,then separate it with Rtx-WAX capillary column and detect it with hydrogen flame ionization detector.This sample is determined in gas chromatograph after purging and traping.The minimum detectable concentration is 0.005 mg/m3,the relative standard deviation is less than 1%,the recovery rate is between 88.20% and 93.00%.The method is simple,sensitive,and has low limit of detection and good degree of separation. |
