[Abstract]:Objective to establish a headspace gas chromatography method for the determination of picric acid in workplace air. [methods] picric acid in air was collected by microporous membrane, eluted with pure water, and detected by electron capture detector (ECD) with sodium hypochlorite derivative headspace gas chromatography. [results] the linear range of picric acid concentration was 0.01 渭 g / mL (r = 0.999 7). The detection limit of this method was 0.000 渭 g / mL (injection volume was 100 渭 L),). The lowest detectable concentration was 0.000 mg/m3 (sample volume was 75 L, desorption volume was 10 m L), relative standard deviation was 1.42 and 1.61%), and the average recovery was 97.9 and 99.7, respectively. The average elution efficiency was 95.9% and 97.3%, the sampling efficiency was 95.1% and 97.1%. The microporous membrane absorbed 10 渭 g picric acid and kept at room temperature for at least 15 days. [conclusion] all the indexes of this method are in line with the requirements of GBZ/T 210.4-2008 guidelines for the Establishment of Occupational Health Standards part 4: methods for the determination of Chemical substances in Workplace Air, which is suitable for the detection of picric acid in workplace air.
