“…Molecularly imprinted polymers (MIPs) are porous matter fabricated via imprinting technology, which has perfect selectivity for the templates in spatial structure and binding sites [7]. According to the location of templates distributed into the imprinted polymers, the MIPs can be classified as traditional bulk MIPs, novel surface MIPs, and epitope MIPs [8]. Bulk MIPs are the first-generation products with imprinting technology, which are prepared with template-functional monomer complex, cross-linkers, and initiators.…”

“…Novel irradiation polymerization was developed for the fabrication of MIPs, especially for the electron beam (EB) irradiation polymerization, which not only shortens the preparation time, but also avoids environmental pollution and initiator residue [8,9]. MIPs of sulfamethazine were prepared by EB irradiation polymerization [18], wherein the optimal irradiation dose was found to be 150 kGy, the maximum adsorption capacity of sulfamethazine was 31 mg/g, and the imprinting factor was as high as 12.91.…”

To realize the selective separation of L-tyrosine (L-Tyr) and avoid the drawbacks of traditional thermal polymerization, electron beam irradiation polymerization was developed for the fabrication of L-Tyr molecularly imprinted polymers (MIPs). Firstly, L-Tyr MIPs were prepared with methacrylic acid and ethylene glycol dimethacrylate and without an initiator. Then, the influence of absorbed dosage and temperature on the adsorption capacity of L-Tyr, as well as the thermodynamic behavior, were investigated. The maximum adsorption capacity of 10.96 mg/g for MIPs was obtained with an irradiation dosage of 340 kGy under 15 °C, and the ΔH0 and ΔS0 of the adsorption process are −99.79 kJ/mol and −0.31 kJ/mol·K, respectively. In addition, the effect of adsorption time on adsorption performance was evaluated under different initial concentrations, and the kinetic behavior was fitted with four different models. Finally, the recognition property of the obtained MIPs was investigated with L-Tyr and two analogues. The obtained MIPs have an imprinting factor of 5.1 and relatively high selective coefficients of 3.9 and 3.5 against L-tryptophan and L-phenylalanine, respectively. This work not only provided an L-Tyr MIP with high adsorption capacity and selectivity but also provided an effective and clean method for the synthesis of MIPs.

“…[73] This also showed that the synthesized MIP (2VP) was more selective The successful imprinting process of MIP significantly contributed to its selectivity towards ATZ, demonstrating remarkable recognition ability despite the minimal structural differences among the competitive compounds, thus highlighting the combined influence of shape and size complementarity alongside analyte-functional group interactions within the three-dimensional polymer network.

“…The molecular imprinting process allows for precise control over the shape, size, and distribution of binding sites within the polymer matrix, enabling tailored interactions with the template molecules [32] . Furthermore, MIPs offer excellent stability, high affinity, high selectivity, simple, and inexpensive preparation, [33] which are crucial factors for sustainable and cost‐effective environmental conservation strategies. Commonly, there are various options for MIP preparation such as traditional thermal polymerization, novel radiation polymerization, and green polymerization and the produced MIPs are useful for numerous applications including separation and detection [34] .…”

Atrazine (ATZ) is a widely used triazine herbicide in agriculture, however, it negatively affects the environment and human health. Therefore, a molecularly imprinted polymer (MIP) was employed for the selective removal of ATZ. In this study, MIPs were produced by precipitation polymerization using ATZ as the target molecule, methacrylic acid (MAA), acrylamide (AAm), and 2‐vinylpyridine (2VP) as functional monomers and ethylene glycol dimethacrylate (EGDMA) as cross‐linker, respectively. MIP characterizations were performed using Fourier Infrared spectroscopy (FTIR) and Field Emission Electron Microscopy (FESEM). The batch binding study revealed that MIP (2VP) exhibited the highest rebinding efficiency (88.44 %) among the MIPs. Furthermore, MIP (2VP) was analyzed by Energy‐Dispersive X‐ray spectroscopy (EDX), Brunauer‐Emmett‐Teller (BET) analysis, and thermogravimetric analysis (TGA). Adsorption studies revealed that the optimum conditions for maximum adsorption efficiency were 8 ppm ATZ solution at pH 7, using 0.3 g of MIP (2VP). MIP (2VP) demonstrated higher selectivity towards ATZ than the Ametryn (AME) a competitive interferent, with a relative selectivity coefficient of 2.77. MIP (2VP) successfully removed ATZ from distilled water (95.39 %), tap water (88.16 %) and river water (86.75 %). These findings contributed for the development of MIP for the removal of ATZ, which would be helpful in the protection of ecosystem and human health in future.

Dispersants, serving as an essential raw material in the formulation of coal water slurry, offer an economical and convenient solution for enhancing slurry concentration, thus stimulating significant interest in the development of novel and efficient dispersants. This paper intends to illuminate the evolution of dispersants by examining both the traditional and the newly conceived types and elaborating on their respective mechanisms of influence on slurry performance. Dispersants can be classified into anionic, cationic, amphoteric, and non-ionic types based on their dissociation properties. They can be produced by modifying either natural or synthetic products. The molecular structure of a dispersant allows for further categorization into one-dimensional, two-dimensional, or three-dimensional structure dispersants. This document succinctly outlines dispersants derived from natural products, three-dimensional structure dispersants, common anionic dispersants such as lignin and naphthalene, and amphoteric and non-ionic dispersants. Subsequently, the adsorption mechanism of dispersants, governed by either electrostatic attraction or functional group effects, is elucidated. The three mechanisms through which dispersants alter the surface properties of coal, namely the wetting dispersion effect, electrostatic repulsion effect, and steric hindrance effect, are also explained. The paper concludes with an exploration of the challenges and emerging trends in the domain of dispersants.
