Preparation and Absorption Property of Graphene Oxide-Based Isoproturon Molecularly Imprinted Polymer

The surface-molecularly imprinted polymer (MIP) was prepared using graphene oxide as carrier and isoproturon as template.Structure of the MIP was characterized by TEM,Raman and TGA analysis.Absorption property of the MIP was studied by dynamic balance combined method.The results showed that the adsorption kinetics could be well described by the pseudo second-order model with correlation coefficient (R2) of 0.999 7.Moreover,compared with non-molecularly imprinted polymer,the MIP showed higher removal rate and rapid adsorption kinetics.The result of selective adsorption showed that MIP displayed selective and specific adsorption to isoproturon.
