Abstract: Monobutyltin molecularly imprinted polymers(MBT-MIPs) which have special molecule recognition ability to monobutyltin (MBT) were synthesized with MBT as template chitosan as the functional monomer and glutaraldehyde as the cross-linker In this paper,the structure of MBT-MIPs was characterized with scanning electronic microscope,and the synthesis conditions of MBT-MIPs,the adsorption properties and selective recognition of MBT-MIPs for MBT were also studied.The experimental results showed that MBT-MIPs had higher adsorption capacity and higher selective recognition for MBT compared to nonimprinted polymers(NMIPs) which had the Similar chemical composition.The maximum adsorption capacity of MBT-MIPs for MBT was 165.9 μg g-1 and the static distribution coefficient for MBT was 10.66.
