Abstract
Objective: To establish a method for the determination of ethylamine in the air of the workplace by ion chromatography. Methods: In August 2020, ethylamine in the air of the workplace was adsorbed by a basic silica gel tube, and ultrasonically desorbed with a 1 mmol/L sulfuric acid solution, and then qualitatively and quantitatively determined by ion chromatography. Results: The linear range of the method was 0.014-50 μg/ml, and the linear equation of the standard curve was y=0.1243x+0.0429, the correlation coefficient was r=0.9997. The detection limit of the method was 4.29 μg/L, and the lower limit of quantification was 14.29 μg/L. The lowest quantitative concentration was 0.012 mg/m(3) (in term of sampling 6.0 L) . The average desorption efficiency of the method was 97.31%, the precision was 1.00%-1.68%, and the standard recovery rate was 96.33%-99.61%. Conclusion: This method is fast, sensitive and accurate, and can be used for the determination of ethylamine in the air of workplace.
