Application research of magnetic molecularly imprinted polymers in sample pretreatment
This study aims to explore the application of magnetic molecularly imprinted polymers in sample pretreat-ment.Gas chromatography tandem mass spectrometry combined with magnetic molecularly imprinted polymers was used to determine the content of naphthalene,phenanthrene,phenanthrene,anthracene,fluoranthene,and pyrene in the sample.Result:Within the mass concentration range of 0.6~48 µg/kg,the correlation coefficients were all greater than or equal to 0.997 0.The detection limit is 0.26~0.48 μg/kg,and the quantification limit is 0.81~1.42 μg/kg.This method can be effectively applied to the detection and analysis of polycyclic aromatic hydrocar-bons in food packaging materials such as takeaway food containers.
