中文摘要：

目的建立水处理剂中丙烯酰胺单体的气相色谱．质谱联用（GC-MS）分析方法。方法样品经柱前溴化衍生2h，3ml混合有机溶剂（乙酸乙酯：正己烷体积比为4：1）进行提取后，进行GC-MS测定。结果在4．3—2000μg／ml线性范围内，丙烯酰胺单体的线性回归方程：y=10774x-305196，相关系数为0．9994。该方法的平均回收率范围在70．2％～109．2％之间，批内RSD在1．00％～7．90％之间，批间RSD为5．0％。结论该方法操作简单、快速，具有较高的准确度和灵敏度，适用于水处理剂中丙烯酰胺单体的测定。

英文摘要：

Objective To develop a method for the determination of acrylamide in floceulant by gas chromatography-mass spectrometry. Methods Acrylamide was derived through bromination and extracted by organic solvent. GC-MS method was used to identify the target substance and quantify acrylamide. Results The recoveries obtained from samples spiked with standards were in the range of 70.2%-109.2% and relative standard deviations （n=5） was less than 5.0%. Linearity of peak area was obtained over a wide range of conc＇entration （4.3-2 000μg/ml）, and the correlation coefficients was 0.999 4. Conclusion The method is reliable, selective and reproducible and it is applicable to the determination of the acrylamide in flocculant.
