Title: Benzene and benzene series in the room air was estimated by solvent relief absorption gas chromatography
Abstract: Using solvent relief absorption gas Chromatography to estimate the concentration of the Benzene and benzene series in the room air.The method: It adopted the active carbon tube to collect samples,which were relieved by CS2 absorption with HP-5 capillary gas chromatography and FID detector.It studied the linearity and calculation factors of the benzene and the benzene series.Results: Regarding peak area as the foundation,linear regression turned all right,it can be accurate fixed the amounts;the benzene,toluene,ethyl benzene,(m,p)-xylene,o-xylene calculation factors respectively for 6.266×10-4、6.527×10-4、6.647×10-4、 5.599×10-4、7.120×10-4.From the students dormitories,dining rooms,restaurants,super markets for Zhejiang forestry University proceeds measurement,results showed that in the above places the benzene concentration measured were all less than 0.09mg/m3,the total concentration of benzene series is far less 0.9mg/m3.
