ABSTRACT

A method for the determination of four acrylate monomers in food packaging paper was established based on high performance liquid chromatography (HPLC) method. The effects of extraction solvent, ultrasonic time, ultrasonic temperature and other pre-treatment conditions on the extraction efficiency of acrylate monomers were investigated. Under the optimal conditions, the samples of food packaging paper were extracted by ultrasonic treatment, analyzed by HPLC, and quantified by external standard method. The results suggested that the four acrylate monomers showed good linearity in the range of 0.1-50.0 mg/L (R2 ≥ 0.999), and the detection limits (LODs) were 0.03-0.08 mg/L. The blank samples were used as the matrix for standard addition experiment, and the recoveries were 89.2%-108.1% with relative standard deviations of 1.3%-4.8%. The method was simple, accurate and reliable, which can provide technical support for daily detection of acrylic monomers in food packaging paper.
