摘要
采用活性碳吸附-二硫化碳解吸,GC-MS法测定空气中丙烯酸酯类污染物,采样体积为2h时,定量下限为0.5～1.6μg/m3。在吸附总量小于5mg时,活性碳吸附效率几近100%。CS2提取效率也都在95%以上。方法相对标准偏差为0.5%～3%,回收率为95%～109%。
This paper is studied the method with adsorbent of activated charcoal and desorption agent of CS2 for determining acrylic esters in the air by GCMS It has good adsorbtion rate and it's desorption rate is good enough too The detection limits are 05～16μg/m3RSD are 05%～3% ,and recovery rate 95%～109% the method is simple and also have high sensitivity and precision
