Atrazine transforming polymer prepared by molecular imprinting with post-imprinting process

摘要: Molecularly imprinted polymers bearing atrazine transforming activity were prepared by using newly designed templates that are analogues attached with an allyl or a styryl group via disulfide bond at the 6-position, methacrylic acid as functional monomer and styrene/divinylbenzene crosslinkers. After polymerization, was reduced to remove moiety from polymer matrix, followed oxidation of remaining thiol generate sulfonic (post-imprinting treatment), so both residue existed in atrazine-imprinted cavity. The indicated selective binding triazine herbicides catalytic for methanolysis 6-position atrazine, yielding low toxic atraton.
