| 目的 建立同时测定包装纸中丙烯酰胺和6种芳香胺迁移量的检测方法。方法 通过筛选固相萃取小柱种类，优化净化方法和液相色谱条件，从而形成丙烯酰胺和6种芳香胺迁移量的固相萃取-高效液相色谱检测方法。结果 丙烯酰胺在0.2~20 mg/L的浓度范围内线性关系良好（R2=0.9989），检测波长为220 nm，检出限为0.01 mg/L；芳香胺在0.2~20 mg/L的浓度范围内线性关系良好（R2＞0.998），检测波长为240和280 nm，检出限也为0.01 mg/L。纯水样品中，各化合物的加标回收率在90%以上，相对标准偏差为2.3%~5.9%。实际样品中，芳香胺的加标回收率在86.9%以上，相对标准偏差为2.0%~6.1%；丙烯酰胺的加标回收率为78.7%~81.9%，相对标准偏差为4.2%~6.2%。结论 该方法处理步骤简单，分离效果好，精密度高，从提高检测效率、节约成本的角度来看，该方法值得推广成为常规检测方法。 |

| The work aims to develop a detection method that can measure the migration of acrylamide and 6 aromatic amines. A solid phase extraction-high performance liquid chromatography (HPLC) was established to measure the migration of acrylamide and 6 aromatic amines, through screening the types of columns based on solid-phase extraction, and optimizing the purification method and liquid chromatography conditions. The acrylamide had a good linear relation (R2=0.9989), the detection wavelength was 220 nm and the limit of detection was 0.01 mg/L when the concentration range was 0.2~20 mg/L. The aromatic amine had a good linear relation (R2＞0.998), the detection wavelength was 220 and 280 nm and the limit of detection was also 0.01 mg/L when the concentration range was 0.2~20 mg/L. In the water sample, the recovery of each compound was above 90% while the relative standard deviation (RSD) was 2.3%~5.9%. In the practical samples, the recoveries of aromatic amines were above 86.9% with 2.0%~6.1% of RSD, while the recovery of acrylamide was 78.7%~81.9% with 4.2%~6.2% of RSD. Featured by simple processing step, good separation effect and high precision, the method is worth being popularized as a routine detection method from the viewpoint of improving detection efficiency and saving cost. |
