Abstract: In this thesis,the molecularly imprinted terpolymer were synthesized using a-methacrylic acid and 4-vinylpyridine as co-functional monomers,ethylene glycol dimethacrylate as crosslinker,azobisisobutyronitrile as initiator,chloroform as porogenic reagent and metsulfuron methyl as template molecules by bulk polymerization.The binding capacity of MIPs in organic and aqueous systems were evaluated by solid phase extration.The binding capacity of terpolymer is 20.5 mg in organic system and 19.2 mg in water system,which is much higher than that of the bipolymers,and is very useful for the recovery from the waste of metsulfuron methyl factory.The proton nuclear magnetic resonance(1H NMR)titration test was further used to study the phenomenon of high capacity,and the results indicated that there was obvious hydrogen bond interaction between MSM and the co-monomers of methacrylic acid and 4-vinylpyridine,which indicated that the stronger sites were formed.
