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.

Neodymium Ion

Neodymium ion imprinted polymers (IIP) were synthesized by formation of ternary complexes of neodymium ion with Vanillin Benzidine(VLB) and 4-vinylpyridine (VP) as chelating agent following copolymerizing with styrene as func­tional monomer and ethylene glycol dimethacrylate (EGDMA) as cross-linking monomer using 2,2´-azobisisobutyronitrile as initiator. Control polymers（CPs） were prepared under identical conditions without the use of neodymium 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 ternary complex of Nd3+–VLB–VP(1:1:2 IIP) showed quantitative enrichment of neodymium ion from aqueous solution.

Cu2+-imprinted polymers (Cu(II)–IIPs) were prepared by thermal precipitation polymerization method with Cu2+ion as the template, 1,4-dihydroxyanthraquinone (AQ) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as a cross-linker. In synthesis processes,The functional monomer AQ, there is only one functional groups that can selectively recognize Cu2+ ion, is set in highly cross-linked polymer net, not to form covalent-linkage with polymer net. The imprinted polymer particles were characterized by UV-visible spectra, FT-IR, scanning electron microscopy and colorimetry. The sorption and selectivity capacity of Cu(II)–IIPs for Cu2+ ion were studied．The results showed that the imprinted polymer had good affinity for Cu2+. The maximum sorption capacity was 11.4 mg/g．The sorption equilibrium time was 50 min and the optimum pH for quantitative copper retention was 7.0. Competitive sorption of Cu2+, Co2+, Zn2+, Mg2+, Ca2+ from their mixture was also studied in a batch system. The relatively selective factor of copper to other metal ions were greater than 1. The Cu(II)–IIPs could be repeatedly used with high selectivity and stability for Cu2+.This Cu(II)–IIPs has been successfully applied to the separation and determination of the trace Cu2+ in real water samples.
