摘要
建立了水性胶粘剂中残留AM(丙烯酰胺)单体的检测方法,即首先利用良溶剂三氯甲烷有效提取水性胶粘剂样品中的AM单体,然后采用毛细管柱分离法、GC-FID(气相色谱-氢火焰离子化检测)法测定提出液中的AM含量。结果表明:当标准样品的浓度为5.0～80.0 mg/L时,采用上述方法测定水性胶粘剂中AM含量时,其重复性良好(相对标准偏差为0.3～2.8 mg/L);以某厂生产的建筑胶粘剂和白胶为例,采用上述方法测定胶样中的AM含量,两者的加标回收率为93%～107%,说明两种样品的回收率良好,其测试结果较为可靠。
To establish testing method for remaining AM（acrylamide） monomer in waterborne adhesives, namely, the AM monomer contents in extracted sample were tested by capillary column separation method, GC-FID（gas chromatography-hydrogen flameionization detector） method when the trichloromethane as good solvent could effectively extracte AM monomer in waterborne adhesives samples. The results showed that the reproducibility of testing AM contents in waterborne adhesive was good by above methods because its relative standard deviation was 0.3-2.8 mg/L when the concentration of standard sample was 5.0-80.0 mg/L. With construction-adhesive and white latex as example,the results of testing AM contents in adhesive samples by above methods were more reliable because the recovery rates of two samples（added between 93%-107%） were all good.
