| 摘 要： | 建立了直接进样测定工业废气中苯乙烯的气相色谱法.工业废气样品通过气体进样阀进入气相色谱仪中进行分离和检测,采用0.25 mL气体进样阀时,方法的检出限为1.4 mg/m3,苯乙烯含量在3.19～51.0 mg/m3时,测定结果的相对标准偏差为2.19％～4.50％(n=5),与行业标准HJ 583-2010,HJ 584-2010相比,该方法操作简便、快速,适合工业废气中苯乙烯的快速测定.

| Abstract: | A method for the determination of styrene in industrial waste gas by GC with direct injection was recommended.Through the gas sampling valve,the industrial waster gas was put into GC to be separated and detected.As 2.5 mL gas sampling valve was used,the detection limit of the styrene was 1.4 mg/m3.As the content of styrene in industrial waster gas were 3.19–51.0 mg/m3,the standard relative deviation of determination results were 2.19% – 4.50%(n=5).Compared with HJ 583–2010 and HJ 584–2010,this method was more simple,fast and suitable for the rapid determination of styrene in industrial waste gas. |
