摘要
研究并建立了毛细柱气相色谱-微池电子捕获检测器测定水中丙烯酰胺的方法。水样中丙烯酰胺经溴化衍生后，用乙酸乙酯萃取，经气相色谱法分析，取l00ml水样时方法检出限为0．017μg／L。丙烯酰胺在0．50～12．50μg／L范围内线性良好，在低、中、高3个添加水平，平均加标回收率为99．3％～114％，相对标准偏差为0．4％-3．5％。本方法准确度高、精密度好，适用于水中丙烯酰胺测定。
A method for the determination of acrylamide in water was established by gas chromatography with bromination derivation. The acrylamide in water sample was derived through hromination and extracted by ethyl acetate, and determined by gas chromatography. The detection limit was O. 017μg/L while the volume of water sample was 100 ml. The result has a good linearity for the acrylamide concentrations between 0. 50 to 12. 50μg/L. The average recoveries were between 99.3% and 114% with RSD of 0. 4% to 3.5%. This method was accurate and precise, and it can be used for the determination of acrylamide in water sample.
