Abstract: Hydrogels of chitosan were synthesised using epichlorohydrin as the cross-linking agent in water solution.These hydrogels could recognise and adsorbed organosulphur.The effects,such as binding capacities,selective recognition of MIP and the factors on polymerization,were discussed.The results showed that,by epichlorohydrin as cross-linking,the molecularly imprinted polymer have highly binding capacities and selective recognition to the DBT. Maximum binding capacities of MIP measure 17.53 mg/g.
