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.

Abstract In this study, a novel functional monomer N-(1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethyl)acrylamide (NDTEA) was designed and synthesized, and was used to prepare Ni(ii) ion-imprinted polymers (Ni(ii)-IIPs). Sixteen kinds of Ni(ii)-IIP (Ni(ii)-IIP1–16) and corresponding non-imprinted polymers (NIP1–16) were prepared by precipitation polymerization method. After optimized condition experiment, Ni(ii)-IIP5 possessed maximum adsorption capacity and better imprinting factor under optimal experimental conditions which indicated by equilibrium adsorption experiments. The morphology and structural characteristics of Ni(ii)-IIP5 were characterized by scanning electron microscopy (SEM) and Brunauer–Emmett–Teller (BET). The adsorption selectivity of Ni(ii)-IIP5 was analyzed by ICP-OES, and the results showed that Ni(ii)-IIP5 had favorable selectivity recognition ability for Ni(ii) when Cu(ii), Co(ii), and Cd(ii) are used as competitive ions. The kinetic experiment indicated that the performance of Ni(ii) adsorption on the surface of Ni(ii)-IIP5 obeyed the pseudo-first-order model, and adsorption equilibrium was attained after 15 min. Isothermal adsorption process fitted to Langmuir and Freundlich isothermal adsorption models, simultaneously. The results showed that Ni(ii)-IIP5 prepared by using a new functional monomer had better permeation selectivity and higher affinity for Ni(ii), which also verified the rationality of the functional monomer design. At the same time, it also provided a broad application prospect for removal of Ni(ii) in complex samples.

Ion imprinted polymers (IIPs) are very difficult to apply in actual wastewater containing solid particles and floccules due to the imprinting hole blockage of losing adsorption performance.
