Abstract: Using Pb(Ⅱ) as the template ion, a precipitation polymerization method was adopted to prepare a series of Pb(Ⅱ)-imprinted polymers Pb(Ⅱ)-IIPs and corresponding non-imprinted polymers (NIPs) by using Fe₃O₄/MIL101(Cr) as the metal organic frameworks (MOFs), ethylene glycol dimethacrylate as the crosslinking agent, and optimizing the experimental conditions such as the amount of MOFs, functional monomer, crosslinking agent, and the type of porogenic solvent. Through scanning electron microscopy (SEM), nitrogen adsorption/desorption (BET), isothermal adsorption and kinetic adsorption experiments, the Pb(Ⅱ)-IIP₈ and NIP₈ prepared under the optimal experimental conditions were structurally characterized and their properties were studied. The results indicated that Pb(Ⅱ)-IIP₈, prepared under the optimized conditions, exhibited a higher adsorption capacity and imprinting factor for Pb(Ⅱ) ions, and it was expected to be used as a new type of Pb(Ⅱ) ion adsorption material.
