摘要
采用活性炭吸附-苯解吸-填充柱色谱法测定酮苯脱蜡车间空气中丁酮和甲苯的含量,在填充柱上丁酮、苯和甲苯可得到完全分离。该方法的准确度和精密度较高,相对误差<5%,色谱平行测定结果的相对偏差<5%,最小检出浓度为1m/m3。
The contents of butanone and toluene in the air at ketone-benzol dewaxing workshop are measured by packed chromatographic column method with activated carbon as an adsorbent and benzene as a desorption agent.Butanone, benzene and toluene can be completely separated in the packed column.This method is characterized by simple and rapid operation,higher accuracy and precision,with less than 5% of relative error,less than 5%.of relative deviation of parallel measurement,and 1mg/m3 of minimum detection limit.
