| Abstract: | We used activated carbon tube to absorb furfural in ambient air,desorbed it with CS2,separated it with Rtx-WAX capillary column and detected it with hydrogen flame ionization detector.The sample was determined with gas chromatograph.The lowest detected concentration was 0.006 mg/m3,recover rate was above 90.00%.The method is simple and sensitive,and it has low limit of detection and good degree of separation. |
