摘　　要：采用气质联用分析法对u-PVC阻燃电工套管热解烟气中苯、甲苯进行分析研究。设定管式炉的加热温度为710℃,在材料产烟毒性装置上进行热解。通过大气采样器(流速1.0L/min),用环己烷溶液吸收u-PVC阻燃电工套管的热解烟气,取离心后的环己烷上层清液进行测试。结果表明:在优化条件下可获得满意的分离度和结果。热解产物主要毒性组分苯浓度为58.33mg/m3,甲苯浓度为34.12mg/m3。Benzene and Toluene in pyrogenation gas of u-PVC flame retardant electrical conduit were analyzed by GC-MS anal- ysis. The heating temperature of tubular furnace was 710℃, the pyrogenation was carried out in the apparatus of gas toxicity of materials. The air sampler （flow velocity of 1. 0 L/s） and cyclohexane were used to absorb the pyrogenation gas of u-PVC flame retardant electrical conduit. The upper clean liquid of cy cIohexane after centrifugalization was tested. The results showed that： under the optimization of analytical conditions, satisfactory resolution and results were obtained. The concen- tration of Benzene was 58.33 mg/m3 , and that of Toluene was 34.12 mg/m3 , which were the main component of pyrogenation gas.
