| 摘 要： | 本文建立了毛细管气相色谱法测定水处理剂聚丙烯酰胺中残留丙烯酰胺的方法。丙烯酰胺经甲醇-水从样品中提取，经KB—WAX（30．0m×250μm×0．25μm）毛细管气相色谱分离，FID检测器测定含量，在0—80mg／L浓度范围内相对标准偏差为4．；5％-6．0％，加标回收率在92％-108％之间.

| Abstract: | In this paper determinated process of the residual acylamide in polyacrylamide Isestabeished with capillary Chromatography,The acylamide was efficiently from sample with methanal-water,then analyzed by gas Chromatographyon a capillary column KB- WAX （30.0m×250μm×0.25μm） and with a flame ionization detector.The relative standard deviation is 4.3%-6.0%,and the recoveries rate with standard addition is 92%-108%. |
