摘要
用活性炭采集大气样品,OV-101(30m×0.32 mm i. d.)弹性石英毛细管柱分离丙烯酸和3种丙烯酸酯类化合物,氢火焰离子化检测器测定,建立了气相色谱法测定大气中丙烯酸及其酯类化合物的方法。该方法有较宽的线性范围,相关系数达到0.996以上,相对标准偏差为3.16％～5.83％,回收率为84.4％～95.4％,检出限为0.003～0.03 mg/m^3(采样体积为20L)。
The method about the determination of acrylic acid & acrylate in air by gas chromatography was set up by using the activated charcoal to absorb acrylic acid and acrylate, OV - 101 (30 m ×0. 32 mm i. d. ) fused-silica capillary column to separate and FID detector to detect. This method has wide linear range, correlation factors are beyond 0. 996, RSD is 3. 16% -5. 83% , the recovery is 84. 4% - 95. 4% and the detection limit is 0. 003 - 0. 03 mg/m3 ( the sampling quantity of air is 20 L) .
