Abstract: Using chitosan as a polymer matrix,trichlorfon as a template molecule,we prepared trichlorfon molecularly imprinted polymers(Tri-MIPs) that match up with template molecules in space structure and the binding sites by molecularly imprinting technique.The synthesis of the Tri-MIPs,including the forces between chitosan and trichlorfon,as well as crosslinking and elution conditions was investigated.In addition the absorption and selective recognition ability of Tri-MIPs to trichlorfon was studied and its structure was charicterized.The result shows that the Tri-MIPs have good capacities of both absorption and selection.The separation factor to omethoate which has a similar structure with trichlorfon reached 3.57.
