摘　　要：使用2,6-对苯基二苯醚多孔聚合物-石墨化炭黑-X复合吸附管采样,采用气相色谱仪和热解析仪,外标法定量测定民用建筑工程室内环境空气中的苯系物。在本方法条件下,苯系物(苯、甲苯、二甲苯)标准曲线线性良好,相关系数(r)均在0.9991~0.9998之间。该方法在民用建筑工程室内空气中苯系物的检测中操作简单,准确度高,重复性好,应用效果良好。Benzene, toluene, xylene in environmental of civil building engineering were determined by external standard method with 2,6-p-phenyldiphenyl ether porous polymer-graphitized carbon black-X composite adsorption tube for sampling adsorption chromatograph and thermal analyzer. Under the conditions of this method, the standard curves of Benzene series(benzene, toluene, and xylene)have good linearity. Compounds were well linear and the correlation coeffioients were all greater than 0.9991~0.9998. This method has simple operation, high accuracy and good application effect in the detection of benzene, toluene, and xylene in the indoor air of civil construction projects.
