“…Therefore, analysis and monitoring of BPA at trace level in complicated environment is very important [2,3] Various analytical methods have been reported for the detection of BPA, such as high-performance liquid chromatography [4] more sophisticated liquid chromatography-mass spectrometry [5], gas chromatography-mass spectrometry [6,7], chemiluminescence immunoassay [8], molecularly imprinted polymers technique [9], enzyme-linked immunosorbent assay [10] and electrochemical methods [1,[11][12][13][14]. Among them, electrochemical methods have advantages of simplicity, high sensitivity, good selectivity and low cost [15][16][17][18][19][20][21][22][23].…”

“…Thus, MIPs can be used to enrich, separate, and purify polyaromatic sulfur-containing compounds from fuels [17,18]. Furthermore, in recent years, surface molecularly imprinted polymers (SMIPs), which are constructed on the surface of supports [19][20][21], are very attractive for adsorptive desulfurization. Identical sites of SMIPs are distributed on the surface of supports, for this reason, mass transfer is accelerated and binding capacity is improved [16,22].…”

Three candidate monomers (methacrylic acid, 2-vinyl pyridine, and 2-acrylamide-2-methyl sulfuric acid) were screened through computational simulation method to prepare effective surface molecularly imprinted polymers (SMIPs) based on carbon microspheres (CMSs) for dibenzothiophene removal from fuels. The optimized structures of complexes were described using density functional theory calculation at B3LYP/6-311??G(d,p) level and frequency calculations for each molecule and complex were conducted to provide insights into electrostatic interaction between monomers and template DBT. Besides, the reliability of computational simulation method for screening was tested by comparing the theoretical data with experimental results from gas chromatography. The computational data suggest that methacrylic acid (MAA) was the preferred monomer with the largest absolute binding energy (14.79 kJ mol -1 ), which is in accordance with the experimental results. Thesaturated adsorption of PMAA-SMIPs/CMSs was the best (41.73 mg g -1 ). Besides, PMAA-SMIPs/CMSs show highest special selectivity for dibenzothiophene against benzothiophene, and the relative selectivity coefficient k 0 was 2.02. The computational simulation method can be effectively used in monomer screening. This work may help understand the mechanisms of polymerization and recognition process between SMIPs and template and design SMIPs with improved adsorption performance.

“…Compared with the conventional bulk polymerization method, surface molecular imprinting explored by generating binding sites on the surface of some matrix materials, was more favorable to increase accessible sites, improve the binding rate between the template molecules and recognition sites, and design the predeterminative imprinted polymers for macromolecules template [14]. Many particles, such as chitosan-Fe 3 O 4 nanoparticles [15], carbon microspheres [16], silica microparticles [17,18], porous alumina membrane [19], and quantum dots [20] have already been reported as reliable supporting matrices in the surface imprinting process.…”

A B S T R A C TNovel strategy to synthesize palygorskite-supported surface molecularly imprinted polymer (SMIP) for bisphenol A (BPA) template was presented. Fourier transform infrared, scanning electron microscopy, and elemental analysis were employed for the characterization of the resulting composites. When compared with the molecularly imprinted polymer, the SMIP exhibited more excellent affinity and selectivity towards BPA in aqueous solution, with the affinity constant (b) of 1.929, the Freundlich constants (K F ) of 25.758, and the distribution coefficient (K d ) of 128.390. The adsorption behaviors of the SMIP were well described by Freundlich isotherm model and the pseudo-second-order model. Moreover, the sustainable reusability of the SMIP without significant loss in rebinding capacity was affirmed in four repeated cycles. These results demonstrated the potential of the prepared SMIP as an advanced separation materials for the elimination of specific endocrine disruptor in aquatic environment.
