摘　　要：用活性炭吸附 CS2(溶剂)解吸气相色谱法监测室内空气中苯、甲苯和二甲苯。对"居住区大气中苯、甲苯和二甲苯卫生检验标准方法 气相色谱法"(GB11737 89)进行了改进,并对改进方法的灵敏度、精确度、准确度、稳定性等进行了测试,结果表明该方法的主要技术指标符合室内环境空气监测的要求。Gas chromatography determination of benzene, toluene and xylene in indoor air by active carbon adsorption-CS_2 (solvent)parse method was studied. According to the national standard of GB11737-89, some conditions were improved, and the accuracy, precision and stability of this method were studied. The results show that this improved method is suitable for determination of benzene, toluene and xylene in indoor air.
