Abstract: Binary complex of imprint ion in design ion imprinted polymer is significant for solid phase extraction. Various of the imprint degree (0.001mmol, 0.01mmol, 0.1 and 1mmol) have been prepared in polymerization. Ion imprinted polymer were prepared via bulk polymerization methods by forming binary complex Zr-Xylenol orange in 2-methoxy ethanol and copolymerizing in the presence of styrene, divinylbenzene and benzene peroxide as an initiator. Zircon ion were removed from polymer particles by leaching with HCl to leave the cavity in the polymer particles, filtering, washing, drying in an oven at 50 °C, and grinding. The polymer particles both prior to and after leaching have been characterized by Optical photo and SEM-EDS, IR. The retention capacity of polymers were found to be 4.6 mg zircon ion per gram particle in pH 6. The decrease of imprint degrees lead to pH of retention on polymer shift to pH acidity. It is also influenced on surface and volume pore, and there was no significant effect on retention capacity and pore size. Zircon-imprinted polymer has been applied to zircon ion extraction and optimum on 0.1 mmol.
