Abstract: The working mechanism of molecularly imprinted polymers (MIPs) for triclosan (TCS) is based on acid-base interaction.The designed MIPs were prepared by thermal bulk polymerization using DMAEMA,DEAM,hydrochloride of AMA,4-VP and MAA as functional monomers,EGDMA and DVB as cross-linkers,AIBN as initiator and acetonitrile as solvent.Adsorption study shows that the MIPs made with DEAM achieve highest adsorption percentage of 78.5% and imprinting factor of 1.7.The selective binding experiments show that DEAM-MIPs show high selectivity to TCS over other structural analogues.Adsorption experiments on TCS by MIPs show that after 5 times of recovery,the adsorption capacity only drops by 5.1%,indicating that the MIPs can be reused multiple times.
