ABSTRACT
Objective:
To establish a gas chromatography method for detecting isobutyl methacrylate in workplace air.Methods:
From July to October 2019, isobutyl methacrylate in workplace air was collected by activated charcoal tube, absorbed using carbon disulfide and analyzed by gas chromatography (FID) with FFAP capillary column.Results:
The linear range of isobutyl methacrylate in the method was 0-800 µg/ml, the correlation coefficient was 0.99993. The detection limit was 0.35 µg/ml. The lowest detected concentration was 0.12 mg/m(3). The within-run precision was 2.06%-2.72%, the between-run precision was 3.03%-3.83%. The rates of desorption was 96.7%. The breakthrough volume was 14.46 mg. The average sampling efficience was 100%. The samples could be stored at room temperature for 7 days.Conclusion:
The method is simple, highly sensitive and precise. Isobutyl methacrylate in workplace air could be determined accurately.Palavras-chave
