We successfully build a standard analytical method for the detection of acetaldehyde, acrylonitrile, and pyridine in water using gas chromatography-flame ionization detector (GC-FID).Three samples with concentration of 0.005 mg/L, 0.05 mg/L and 0.50mg/L were analyzed and showed a high recovery rate between 82%and 98%and a low relative standard deviation from 2.4%to 5.0%. These results confirm that this method has high accuracy, high precision and high reproducibility, which, consequently, is appropriate for detecting and analyzing acetaldehyde, acrylonitrile, and pyridine in water.
