Facile Synthesis of Dopamine-based Magnetic Molecularly Imprinted Polymers for Selective Recognition and Enrichment of Aflatoxin B in Food Matrices before HPLC Analysis
CHEMISTRY LETTERS(2022)
Abstract
A novel sorbent for the enrichment of aflatoxin B1 and B2, of dopamine to attach aflatoxin B1 as the template onto the surface of Fe3O4 nanoparticles. Various parameters affecting the adsorption efficiencies of the prepared polymers were investigated. It can be shown to be an efficient and fairly specific sorbent coupled with UPLC-FLD with a large volume flow cell for the recognition and determination of both aflatoxin Bs in food samples.
