【摘要】：目的建立工作場(chǎng)所空氣中1-溴丙烷(1-BP)和2-溴丙烷(2-BP)的溶劑解吸-氣相色譜同時(shí)測(cè)定方法。方法采用活性炭管采集空氣樣品,以二硫化碳溶液解吸,DB-FFAP毛細(xì)管色譜柱分離,火焰離子化檢測(cè)器測(cè)定。結(jié)果 1-BP和2-BP分別在37.24~2 979.00和16.38~1 310.00 mg/L范圍內(nèi)線性關(guān)系良好,相關(guān)系數(shù)均大于0.999 99。4℃冰箱中放置過(guò)夜時(shí),1-BP和2-BP平均解吸效率分別為95.30%~96.14%、99.79%~100.76%,批內(nèi)精密度分別為0.28%~0.68%和0.24%~0.38%,批間精密度分別為0.97%~1.68%和1.28%~1.61%。100 mg活性炭管的1-BP和2-BP平均穿透容量分別大于2.9、2.5 mg。1-BP和2-BP樣品在室溫下分別至少可保存1和16 d,在4℃冰箱中分別至少可保存10和45 d。結(jié)論本方法適用于工作場(chǎng)所空氣中1-BP和2-BP的同時(shí)測(cè)定。
[Abstract]:Objective to establish a method for simultaneous determination of 1-bromopropane (1-BP) and 2-bromopropane (2-BP) in workplace air by solvent desorption and gas chromatography. Methods the air samples were collected by activated carbon tube and separated by DB-FFAP capillary column with carbon disulfide solution, and were determined by flame ionization detector. Results the linear range of 1-BP and 2-BP was 37.24 ~ 2 979.00 and 16.38 ~ 1 310.00 mg/L, respectively. The average desorption efficiency of 1-BP and 2-BP were 95.3030 ~ 96.14 and 99.79 ~ 100.76, respectively. The intra-batch precision was 0.28 ~ 0.68% and 0.24 ~ 0.38 respectively. The precision between batches was 0.971.68% and 1.28 ~ 1.61.100mg, respectively. The average 1-BP and 2-BP penetration capacity of activated carbon tube were 0.971.68% and 1.28 ~ 1.61.100mg, respectively. At least 1 and 16 days at room temperature, and at least 10 and 45 days in refrigerator at 4 鈩，
