Molecularly imprinted polymers of allyl-β-cyclodextrin and methacrylic acid for the solid-phase extraction of phthalate

► Novel molecularly imprinted polymers were prepared using allyl-β-cyclodextrin. ► The functional monomers were selected by ultraviolet spectrophotometry. ► Polymers adsorption properties were tested by adsorption experiments. ► β-Cyclodextrin enhance adsorption capacity and selective adsorption.
