摘　　要：目的建立工作场所空气中1-溴丙烷的气相色谱测定法。方法应用活性炭管采集工作场所空气中1-溴丙烷，二硫化碳溶剂解吸后，气相色谱-火焰离子化检测器测定，以保留时间定性，以峰面积定量。结果该方法线性范围为2．50—500．00μg／ml，回归方程为y=3553．4x-10064，相关系数R：0．9998，检出限为0．25μg／m]，1-溴丙烷最低检出浓度为0．14mg／ms（以采集1．8L空气样品计）。平均加标回收率为96．8％～102．6％，平均解吸效率为93．2％～104．4％，批间和批内相对标准偏差〈10％，样品在室温下可保存5d。结论该方法适用于工作场所空气中1-溴丙烷的测定。Objective To establish a method for determination 1-bromopropane （1-BP） in workplace air by gas chromatography-flame ionization detector （GC-FID）. Method 1-bromopropane in workplac~ air was collected with activated charcoal tube, then desorbed by carbon disulfide and determined by GC-FID. 1- bromopropane was quantitatively measured using retention time and peak area. Results Linear regression formula was Y =3353.4x-10064 in a range of 2.50-500.00 Ixg/ml with regression coefficient R =0.9998, Detection limit was 0.25 Ixg/ml and the lowest detection concentration of 1-brmopropane in air was 0.14 mg/m3 （at air volume 1.8L）. The mean recoveries of 1-BP were between 96.8% and 102.6%, and relative standard deviation of inter and intra-assay was less than 10%. The average desorption efficiencies were between 93.2% and 104.4%. The samples in activated charcoal tube could be stably stored for 5 days at room temperature. Conclusion The method could be feasible to determine 1-bromopropane in workplace air.
