水溶液中2-氰基吡啶的氣相色譜分析 |
| 肖景嫻(上海石油化工研究院) |
| 摘 要：采用氣相色譜法,選用加堿的PEG 20M不銹鋼填充柱及預柱,以3 氰基吡啶為內標物,測定2 氰基吡啶水溶液含量。方法的標準偏差為0.006,回收率為99.44%～101.28%。方法準確、簡(jiǎn)便快速,適用于生產(chǎn)中質(zhì)量控制。 |

| Determination of 2-cyanopyridine in water by Gas Chromatography |
| XIAO Jing-xian （Shanghai Research Institute of Petrochemical Technology; Shanghai201208; China） |
| 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. |
