“…The result obtained for the adsorption capacity was 76.06, 52.36, and 34.36 μmol/g for MIP‐MS with AA, MIP‐MS with VBA, and MIP‐MS with 4‐VP, respectively. The IF is a quantification of the interaction strength between the template molecule and polymer 54 . The IF values are a ratio between the distribution coefficient of MIP with NIP 54 .…”

Sample preparation was carried out for the removal of interfering substances in the complex matrix sample. Molecularly imprinted mesoporous silica (MIP-MS) is the specific adsorbent used in the sample preparation for solid-phase extraction. MIP-MS can increase the binding capacity, selectivity, and site accessibility of the molecular target. MIP-MS was synthesized using several materials, such as a silica precursor, surfactant, organosilane, functional monomer, and template molecule. Each material influences the formation and analytical performance of the MIP-MS. This review discusses the factors affecting the analytical performance in MIP-MS synthesis, such as the template molecular concentration, the ratio of the silica precursor and organosilane concentration, the type of functional monomer, and the functional monomer concentration. In addition, factors affecting the analytical performance in the adsorption-desorption study, such as pH, mass sorbent, eluting solvent, and washing solvent, to reach high-analyte recovery are also described.

“…The former was linear distribution model and the latter followed the adsorption isotherm model. Some studies showed that pH affected the adsorption of PAHs on soils and the adsorption capacity would be decreased with the increased pH 25 . In addition, temperature was another important factor in the adsorption and desorption behavior of PAHs.…”

Adsorption desorption is an important behavior affecting the migration of phenanthrene in soil. In this study, three typical soils of loess, silts and silty sand in Guanzhong Basin, Shaanxi Province, China were used as adsorbents. Batch equilibrium experiments were carried out to study the adsorption desorption kinetics and isotherm of phenanthrene in different soils. Response surface method (RSM) was used to study the effects of temperature, pH, phenanthrene concentration and organic matter content on soil adsorption of phenanthrene. The results showed that after adsorption, the outline of soil particles became more blurred and the degree of cementation increased. The kinetic adsorption of phenanthrene by soil conforms to the quasi second-order kinetic model, and the adsorption desorption isotherm is nonlinear and conforms to the Freundlich model. Due to the difference of soil properties, the adsorption amount of phenanthrene by soil is loess > silty sand > silts. The thermodynamic results show that the adsorption of phenanthrene by soil is spontaneous and endothermic, and the desorption is spontaneous and exothermic. Through RSM, the interaction between phenanthrene concentration and soil organic matter in Loess and silts is significant, and the interaction between temperature and soil organic matter in silty sand is significant. Among the four factors affecting the adsorption rate of loess, silts and silty sand, soil organic matter is the most significant. The theoretical optimum adsorption rates of loess, silts and silty sand are 98.89%, 96.59% and 93.37% respectively.

“…Then, many studies have reported CIP-MIP synthesis by using different functional monomers, such as methacrylic acid [ 1 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ], 2-vinylpyridine [ 32 ], 1-vinyl-3-ethylimidazolium bromide [ 33 ], and 4-vinylbenzoic acid [ 3 ]. CIP imprinted materials were applied for adsorption [ 34 ] or detection of trace CIP residues in various biological and environmental samples using chemosensor and biosensor [ 35 ], electrochemical sensor [ 36 , 37 ], and optosensor [ 38 ] techniques. Furthermore, Tarly et al proposed using semi-empirical quantum chemistry stimulation for synthesizing CIP-MIP.…”

Background: Ciprofloxacin (CIP), an important broad-spectrum fluoroquinolone antibiotic, was often used as a template molecule for the preparation of imprinted materials. In this study, methacrylic acid and 2-vinylpyridine were employed for the first time as dual functional monomers for synthesizing ciprofloxacin imprinted polymers. Methods: The chemical and physicochemical properties of synthesized polymers were characterized using Fourier transform-infrared spectroscopy, thermogravimetric analysis-differential scanning calorimetry, scanning electron microscopy, and nitrogen adsorption-desorption isotherm. The adsorption properties of ciprofloxacin onto synthesized polymers were determined by batch experiments. The extraction performances were studied using the solid phase extraction and HPLC-UV method. Results: The molecularly imprinted polymer synthesized with dual functional monomers showed a higher adsorption capacity and selectivity toward the template molecule. The adsorbed amounts of ciprofloxacin onto the imprinted and non-imprinted polymer were 2.40 and 1.45 mg g−1, respectively. Furthermore, the imprinted polymers were employed as a selective adsorbent for the solid phase extraction of ciprofloxacin in aqueous solutions with the recovery of 105% and relative standard deviation of 7.9%. This work provides an alternative approach for designing a new adsorbent with high adsorption capacity and good extraction performance for highly polar template molecules.
