摘要: Abstract Molecularly imprinted polymeric membranes (MIPMs) were prepared from cellulose and 1,2- dihydroxybenzene as a print molecule with imprinting ratio of 0.5 1.0. Those applied to the separation xylene isomers by pervaporation. The molecularly selectively incorporated o-xylene o-/m- o-/p- mixtures at low concentration region, adsorption selectivity toward was determined be 7.15 4.24, respectively, implying that 1,2-dihydroxybenzene worked well for recognition; pervaporation carried out 40 °C downstream pressure 0.5 kPa showed permselectivity concentrations while m- p-xylene high concentrations. gave higher flux than control non-imprinted membrane. results obtained in present study revealed molecular is one promising methods prepare
