N2 - A new Zn(II)-ionic imprinted polymer via precipitation polymerization using 8-hydroxyquinoline (8HQ) as a ligand, methacrylic acid (MAA) as functional monomer, and ethylene glycol dimethacrylate (EGDMA) as a cross-linker has been prepared. The benzoyl peroxide and ethanol/acetonitrile (2:1) mixture were used as initiator and porogen, respectively. The template Zn(II) ion was removed from the polymer by leaching with a solution of 1 M HNO3. The experimental parameters for adsorption, such as pH of a solution, contact time, and initial zinc concentration, have been optimized. The optimum conditions of zinc adsorption onto the ionic imprinted polymer (IIP) was at pH 5.5 and contact time 15 min. The equilibrium data could be better described by the Langmuir isotherm model. The maximum adsorption capacity of IIP was 20.833 mg/g.
