摘要
采用气相色谱法,选用加碱的PEG 20M不锈钢填充柱及预柱,以3 氰基吡啶为内标物,测定2 氰基吡啶水溶液含量。方法的标准偏差为0.006,回收率为99.44%～101.28%。方法准确、简便快速,适用于生产中质量控制。
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.
