Comparison between two commercial uranium resins and a uranyl sulphate imprinted resin based on self-assembling MIT

LIU Yaochi, XU Wei, XU Weijian, LIU Hanmao, ZHANG Xiaowen

《化学科学与工程前沿（英文）》 2007年第1卷第4期页码 327-331 doi: 10.1007/s11705-007-0059-8

摘要： In recent years, resins prepared via molecular imprinting technology have received considerable attention owing to their recognition and selective adsorption. This paper deals with the comparative investigation between a uranyl sulphate imprinted ion-exchange based on self-assembling molecular imprinting technology and two kinds of commercial uranium resins (the medium pore resin D263 and strong base resin 201×7). The studies were focused on their kinetics performance, adaptability toward pH, and performance of saturation and elution in laboratory-scale column. The results show that the imprinted ion exchange resin has the fast kinetics, high adaptability toward pH, and good adsorption and elution performance.

Ionically Imprinting-Based Copper (Ⅱ) Label-Free Detection for Preventing Hearing Loss Article

Huan Wang, Hui Zhang, Xiaoli Zhang, Hong Chen, Ling Lu, Renjie Chai

《工程（英文）》 doi: 10.1016/j.eng.2023.09.001

摘要：

Copper is a microelement with important physiological functions in the body. However, the excess copper ion (Cu²⁺) may cause severe health problems, such as hair cell apoptosis and the resultant hearing loss. Therefore, the assay of Cu²⁺ is important. We integrate ionic imprinting technology (IIT) and structurally colored hydrogel beads to prepare chitosan-based ionically imprinted hydrogel beads (IIHBs) as a low-cost and high-specificity platform for Cu²⁺ detection. The IIHBs have a macroporous microstructure, uniform size, vivid structural color, and magnetic responsiveness. When incubated in solution, IIHBs recognize Cu²⁺ and exhibit a reflective peak change, thereby achieving label-free detection. In addition, benefiting from the IIT, the IIHBs display good specificity and selectivity and have an imprinting factor of 19.14 at 100 lmol∙L^–1. These features indicated that the developed IIHBs are promising candidates for Cu²⁺ detection, particularly for the prevention of hearing loss.

Selective removal of Cu(II) from contaminated water using molecularly imprinted polymer

QI Jingyao, LI Xin, LI Ying, ZHU Jianhua, QIANG Liangsheng

《化学科学与工程前沿（英文）》 2008年第2卷第1期页码 109-114 doi: 10.1007/s11705-008-0019-y

摘要： A synthetic molecularly imprinted polymer (MIP) was prepared by noncovalent imprinting technique for the selective removal of Cu from aqueous solutions. In the preparation of imprinted polymer, Cu was used as the template, oleic acid as the functional monomer and divinylbenzene as the cross-linker. The surface morphologies and characteristics of the MIP were determined by BET, scanning electron microscopy (SEM), FTIR and energy dispersive X-ray spectrometer (EDS). The proper adsorption and selective recognition ability of the MIP were studied by an equilibrium-adsorption method. In general, the removal efficiency of Cu increased rapidly with pH from 2 to 7 and decreased at a pH 8. The removal efficiency of Cu increased with temperature from 25°C to 50°C. Competitive adsorption studies showed that the coexisting cations have no obvious influence on the adsorption of Cu. In addition, the variation in the adsorption ability of the MIP that was repeatedly used was investigated, and it showed excellent reproducibility.

Surface molecularly imprinted polymers for solid-phase extraction of (--)-epigallocatechin gallate from toothpaste

Yunling Gao,Ying Hu,Kejian Yao

《化学科学与工程前沿（英文）》 2015年第9卷第4期页码 467-478 doi: 10.1007/s11705-015-1526-2

摘要： Surface molecularly imprinted polymers (SMIPs) have been synthesized to selectively determine (−)-epigallocatechin gallate in aqueous media. SMIPs were prepared using a surface grafting copolymerization method on a functionalized silica gel modified with -cyclodextrin and vinyl groups. The morphology and composition of the SMIPs were investigated by scanning electron microscopy, Fourier transform-infrared spectroscopy and thermogravimetric analysis. In addition, the molecular binding capacity, recognition properties and selectivity of the SMIPs were evaluated. The imprinted polymers were found to have a highly specific recognition and binding capacity for (−)-epigallocatechin gallate in aqueous media which is the result of the hydrophobic properties of the -cyclodextrin and the hydrogen-bonding interactions of methacrylic acid. The SMIPs were successfully employed as solid-phase extraction adsorbents prior to the HPLC determination of (−)-epigallocatechin gallate in toothpaste. The HPLC analysis had a linear dynamic range of 0.5–50.0 µg?mL with a correlation coefficient of 0.9998 and the recoveries ranged from 89.4% to 97.0% with relative standard deviations less than 4.8%. The limit of detection and limit of quantification were 0.17 and 0.33 µg?mL , respectively. The method provides a promising approach for the preparation of selective materials for the purification and determination of complex samples.
