| Abstract: | A simple and sensitive gas chromatography method for determining 2-Picoline in air ambient was established which activated by carbon tubes and desorpted by methanol.The detect limits of this method is consistently bellowed 1.8×10-3 mg/m3, the linear correlated coefficient(r)is 0.999 6, and with recoveries from are ranged 82% to 84%, and the RSD was between 1.3% and 2.9%.The method is simple,less interference,accurate and highly reproducible, suitable for determining the 2-Picoline in air ambient. |
