Abstract
Acrylonitrile (AN) is highly flammable, colorless liquid with an unpleasant odor. Acrylonitrile is used in industry to produce polyacrylonitrile (PAN) and its copolymers. Acrylonitrile can cause cancer. The aim of this study was to develop a method for determining acrylonitrile in workplace air which will allow determination of its concentrations at the level of 0.1 mg/m3 . The method was based on adsorption of acrylonitrile vapors on activated carbon, desorption with acetone solution in carbon disulfide and chromatographic analysis of the obtained solution. The study was performed using a gas chromatograph (GC) with a flame ionization detector (FID) equipped with a DB-VRX capillary column (60 m × 0.25 mm, 1.4 µm). The method was validated in accordance with the requirements of Standard No. EN 482. The method allows the determination of acrylonitrile in workplace air at the concentration range from 0.1 to 2 mg/m3. The method for determining acrylonitrile has been recorded in the form of an analytical procedure (see Appendix). This article discusses the problems of occupational safety and health, which are covered by health sciences and environmental engineering.
