摘要
用串联的乙醇吸收管收集环境空气中的氯化苄和甲苯 ,以毛细管柱分离 ,氢火焰检测器测定 ,保留时间定性 ,峰高定量。氯化苄平均浓度为 4 2 9mg/L～ 2 1 4mg/L时 ,相对标准差在 3 3%～ 4 6 %之间 ;甲苯平均浓度为 4 18mg/L～ 2 0 6mg/L时 ,相对标准差在 4 4%～ 7 8%范围内。方法快速、灵敏度高 ,有较好的精密度与准确度。
Benzyl chloride and toluene were absorbed by alcohol in series tubes, separated by capillary column, detected by FID. The chemicals were identified by retention time, quantified with peak height. Relative standard deviation for benzyl chloride was in the range of 3 3%～4 6% when the concentration was in the range of 4 29 mg/L～21 4 mg/L; relative standard deviation for toluene was in the range of 4 4%～7 8% when the concentration was in the range of 4 18 mg/L～20 6 mg/L. The method was fast, sensitive and accuracy.
