摘要:
The aim of this work was to develop a fluorescence method based on the polydopamine-polyethyleneimine (PDA-PEI) copolymerization, which was subsequently applied for the determination of 3-monochloropropane-1,2-diol (3-MCPD) in food contact papers (FCMs). PEI could provide an alkaline environment and then react with dopamine (DA) to produce copolymers by Michael addition and Schiff-base reactions. This copolymer has a strong fluorescence emission at 527 nm. We found that amino groups of DA and PEI could also react with 3-MCPD in an alkaline medi...
