摘    要:采用活性炭吸附—CS2解析毛细管气相色谱法,对建材市场空气中的苯、甲苯、二甲苯进行了测定。采用活性炭管采集样品,经CS2解析,FID做检测器,考察了苯、甲苯、二甲苯的线性关系。经实验测得解吸率在90%以上,苯、甲苯、二甲苯的加标回收率在96.6%~102.1%,线性方程的相对系数在0.999以上。该方法采样装置体积小、噪音低、操作简便,适用于同时进行苯、甲苯、二甲苯的快速测定。

关 键 词:气相色谱法    甲苯  二甲苯

Abstract:Benzene,toluene and xylene in building materials market air were determined by using activated charcoal adsoption-CS2 analysis capillary vessel gas chromatography. Activated carbon tube was used to collect samples with FID detector. Linearity of benzene,toluene and xylene were studied,results showed that after process experiment,samples desorption rate was above 90%,Canadian sign returns ratio of benzene,toluene and xylene was 96.6%~102.1%,relative coefficient of linear equation above 0.999. The sampling de...
Keywords:gas chromatography  benzene  toluene  xylene
