Abstract: The invention provides a preparing method of Tetracycline molecular imprinting column. The invention includes the following steps: dissolving template molecular Tetracycline (TC) with ultrasound in methanol, adding functional monomer and pore-forming agent (cyclohexanol and lauryl alcohol), oscillating for 6 hours, adding crosslinking agent (ethylene glycol dimethacrylate) and initiator (azobisisobutyronitrile), after ultrasonic degassing, adding nitrogen for 20 minutes, deoxidizing, pouring the solution into 10cm stainless column with bottom sealed, sealing the top end, putting the column into 60 DEG C water for water bath, after 12 hours, obtaining the molecular imprinting column by heat initiation reaction. Connecting the column to the high-pressure pump for washing away the pore-forming agent and template molecular, in the end the molecular imprinting column with good separation effect is obtained. Compared with traditional bulk polymerization method, the invention has the characteristics of simple preparation for avoiding process of lapping, good molecular recognition ability and so on. The molecular imprinting column provided by the invention is used as a liquid chromatogram filling, and can realize separation, enrichment and purification of Tetracycline antibiotics.
