Abstract：A GC method for determination of 2-cyanopyridine in aqueous solution was developed. The column was filled with 5%PEG-20M+2%KOH, and 3-cyanopyridine was used as internal standard. The standard deviation is 0.006 , the recovery rate are 99.44%～101.28%. This method is proved to be rapid, accurate and practical.
