摘要
Abstract
[ Objective ] Using solvent desorption gas chromatography to estimate the concentration of the benzene series chemicals in room air. [ Methods ] Charcoal absorption and carbon disulfide desorption were used for the sampling of benzene series chemicals and analysis was performed by gas chromatography ( DB-FFAP column, FID ). [ Results ] Benzene, toluene,ethylbenzene, o-xylene, m-xylene, and p-xylene were well separated in the DB-FFAP column. The correlation coefficients of regression curves of benzene series chemicals were all greater than 0.9999. The concentration of the quality control samples was within the framework of the certified value. The relative standard deviation 0.55％-0.87％ was obtained. The efficiencies of carbon disulfide deserption were between 90.5％-101.5％. The total xylene concentrations of the bedroom, sitting room and study room in a newly renovated house were exceeding 0.20 mg/m3, while the concentrations of benzene, toluene, and ethylbenzene were low.[ Conclusion ] The method is compatible with concentration detection of benzene series chemicals in room air.关键词
