“…When quercetin was used as interfering substance, the MIP microspheres were placed in a 10 ml of ethanol solution containing quercetin and kaempferol (the initial concentration of quercetin and kaempferol were both 50 mg L −1 ). The concentration of quercetin and kaempferol in the mixture solution were measured by the double-peak dual-wavelength method [ 22 ] using the UV–vis spectrophotometer. The maximum absorption wavelengths of kaempferol and quercetin were 367 and 373 nm, respectively, after further work, the concentration of kaempferol and quercetin in the mixed solution were measured by the simultaneous Equation ( 1 ) as following:…”

A new kind of molecularly imprinted polymer (MIP) microspheres for the selective extraction of kaempferol was prepared by precipitation polymerization using 4-vinylpridine (4-VP) and ethylene glycol dimethacrylate (EDMA) as functional monomer and cross-linker respectively. The synthesis conditions, such as ratios of 4-VP/EDMA and polymerization time were discussed in detail. Results showed that the 2% was the optimal concentration of co-monomers to obtain monodisperse MIP microspheres, the best ratio of 4-VP/EDMA was 1:2, and 24 h was considered as the proper polymerization time. Compared with the MIP agglomeration or coagulum particles, monodisperse MIP microspheres showed the better adsorption capacity: the saturated adsorption capacity of monodisperse MIP microspheres was 7.47 mg g−1, the adsorption equilibrium could be obtained in 30 min. Finally, the adsorption performances of the optimal MIP microspheres were evaluated by kinetic adsorption, adsorption isotherm, and selective adsorption experiments, which indicated that the adsorption mechanism were chemical single layer adsorption and the separation factor was up to 3.91 by comparing with the structure similar compound (quercetin). The MIP microspheres exhibit prospects in the kaempferol efficient and selective separation.

“…The adsorption capacity of Cu‐IIPs was calculated by Equation (1). 22

Q = ((), C_{i} - C_{f}) \frac{V}{W}

where C i (ppm) is the initial concentration of Cu 2+ solution, C f (ppm) is the final concentration of Cu 2+ solution, V (L) is the volume of solution, and W (g) is the weight of the Cu 2+ ions on the polymer particles used.…”

Novel copper (II) ion‐imprinted polymers (Cu‐IIPs) were synthesized by bulk polymerization using 1 mmol of copper (II) sulfate pentahydrate as the template ion, 1 mmol of ethylenediaminetetraacetic acid (EDTA) as the ligand, and 4 mmol of 4‐vinyl pyridine (4‐VP) or methacrylic acid (MAA) as the functional monomer dissolved in a porogen of 20 mL of methanol. Polymerization was performed with 20 mmol of pentaerythritol triacrylate (PETA) as the crosslinker and 1 mmol of benzoyl peroxide as the initiator. The effect of pH, time, initial concentration of Cu2+, and selectivity tests on the adsorption capacity were investigated using flame atomic absorption spectroscopy (FAAS). The prepared polymers were characterized by Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) analysis, scanning electron microscopy (SEM) and X‐ray diffraction (XRD). Adsorption capacity of Cu‐IIPs prepared with MAA increased from 0.794 to 2.163 mg g−1 at pH 6 within 24 hours, while Cu‐IIPs from MAA had high recognition ability with better recognition of Cu2+ than other ions. Thus, these Cu‐IIPs demonstrated potential application as an adsorbent for efficient removal of Cu2+ from aqueous solutions.

“…And the molecular imprinted polymers (MIPs), which possess complementation spatial shape and binding site for a template molecule have gained great attention in the field of analytical chemistry for the past decade [1,2,3] . Because MIPs have predetermined selectivity, recognition and feasibility [4,5] , they have been used in many fields such as chromatography and solid phase extraction [6,7] .…”

The combinatorial molecularly imprinted polymer was prepared by using norfloxacin-Zn (II) complex as a template molecule, amethacrylic acid as a functional monomer in this article. The imprinted sites of the polymer were characterized by Infrared spectroscopy. The analysis results indicated that the metal coordination complex was formed by the 3-carbonxyl group and 4-carbonyl of the norfloxacin and carboxyl of the a-methacrylic acid and the hydrogan bonds was combined by the 3-hydroxy of norfloxacin and carboxyl of another a-methacrylic acid. Besides the selective recognition experiments showed that polymer exhibited significant adsorption selectivity for norfloxacin.
