Abstract Ion imprinted polymer, a kind of high molecular organic polymer, which can separate and enrich various metal ions in water by changing the adsorption conditions. Used humic acid as raw materials, used HNO3 and H2SO4 as modifiers to synthesize nitrosulfonated humic acid, then used it as substrate, NIPAM as the functional monomer, Pb2+ as the template ion, MBA as the crosslinking agent, K2S2O8 and NaHSO3 as initiators to prepare lead ion imprinted polymers after cross-linking reaction. Used SEM, FT-IR, TG-DSC to characterize the obtained product, and explored the structure and performance of the product. The adsorption performance of IIPs (NSA/NIPAM) was studied by ultraviolet-visible spectrophotometry (UV-vis). The results show that the maximum adsorption capacity of IIPs (NSA/NIPAM) for Pb2+ is 81.33 mg/g, the optimal number of cycles of IIPs (NSA/NIPAM) is 10, In the presence of competing ions Cu2+ and Cd2+, selectivity coefficients are 18.04 (Pb2+/Cu2+) and 19.39 (Pb2+/Cd2+). The results of simulating the thermodynamic adsorption process of the polymers with Langmuir and Freundlich thermodynamic adsorption models show that the imprinted polymer conform to the second-order kinetic model and the Langmuir thermodynamic model, and belong to monolayer chemisorption.

A new ion-imprinted polymer (IIP) material was synthesized by copolymerization of 4-vinylpyridine(VP) as monomer, ethylene glycol dimethacrylate(EGDMA) as crosslinking agent and 2,2΄-azobisisobutyronitrile(AIBN) as initiator in the presence of Pb–1,5-diphenylcarbazone(Pb-DHCB) complex. Blank non-imprinted polymer (NIP) were prepared under identical conditions without the use of lead imprint ion. The synthesized polymers were characterized by IR spectroscopy and elemental analyzer techniques. Of the several polymers synthesized, only the imprinted polymer formed with binary complex of Pb2+–DHCB showed quantitative enrichment of lead ion from aqueous solution. The relative standard deviation of the five replicate determinations of Pb (II) was3.26%. The detection limit for 150 mL of sample was 1.6 µg L-1 using flame atomic absorption spectrometry. The developed method was successfully applied to the determination of trace lead in environmental samples with satisfactory results.
