Atrazine imprinted synthetic polymers were prepared using a combination of methacrylic acid and 2-sulfoethyl methacrylate that bound and converted atrazine and other 6-chlorotriazine herbicides to less toxic compounds. A chloride at the 6-position of the triazines was converted to a methoxy group by the polymer in a methanol-containing solvent, where the imprinting effects enhanced the catalytic activity. Competitive inhibition of the atrazine methanolysis was observed in the presence of a structurally related binder, ametryn, suggesting that the catalytic reaction proceeded in the binding sites generated by the molecular imprinting process.

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