| Abstract: | A method for the analysis of acetic acid and propionie acid in tile gas by GC-FID was set up. Acetic acid and propionic acid in the gas was adsorbed by silicon tube,desorbed by acetone and then determined by GC. The ealibration at the eoncentration range 20 ～ 2 000 mg/L was linear by the optimized method. The detection limit was 1.0 mg/m^3 and 0.5 mg/m^3. The relative slandard derivations was 2.2% and 1.9% ,and Ihe recovery was higher than 94%. |
