“…It was observed that the vibration peak at 1630 cm −1 corresponding to the stretching vibration of C=C in MPS further proved that SiO 2 @Fe 3 O 4 was successfully grafted with MPS. Those results are consistent with that of other researches [40,41].…”

“…The increase in hydroxyl groups can improve the surface wettability and strengthen the interaction of hydrogen bond . In addition, a silica surface is easy to be modified through the covalent reaction . Finally, vinyl groups were introduced onto the surface of activated SiO 2 @Fe 3 O 4 via MPS coupling, which offered reaction sites for further radical polymerization.…”

“…Subsequently, cross‐linker DVB (4.0 mmol) and initiator azodiisobutyronitrile (0.06 mmol) were added into the system and the mixture was degassed in an ultrasonic bath for 5 min. After that, it was purged into nitrogen gas for 10 min to remove oxygen; the polymerization system was carried out at 60°C with nitrogen protection for 24 h. The final product was collected with a help of an external permanent magnet and the particles were washed sequentially with methanol/acetic acid solution (9:1, v:v) to remove the entrapped template until there was no template being detected by UV‐Vis spectroscopy. The synthesis procedure of AO‐imprinted MMIPs was shown in Figure .…”

A novel magnetic molecularly imprinted polymer for the selective recognition of auramine O was rationally designed via screening from a library of nonimprinted polymers. A stoichiometric ratio of functional monomer (itaconic acid) and template molecule (auramine O) was found to be 1.5. Meanwhile, the synthesized SiO @Fe O was modified by 0.5 mol/L hydrochloric acid to facilitate the preparation of magnetic molecularly imprinted polymer particles. Adsorption experiments showed that the magnetic polymer particles exhibited good selectivity, recoveries, and enrichment performance. The stoichiometric imprinted polymers have been employed for the selective preconcentration of auramine O from lake water sample. The high specificity of the stoichiometric imprinted polymers was proven in the extraction of mixture solution of auramine O, auramine O hydrochloride, and chrysoidine, and the recoveries ranged between 99.66 and 108.75% (RSD 2.6-3.7%, n = 3) for lake water. These results suggest that this method is effective and can be successfully applied to the analysis of auramine O in environmental water samples.

Lime juice as the most commonly used natural source production can be characterized using determination of flavonoids contents such as hesperidin. So, development of analyzing methods for checking the quality and healthiness of lime juices is necessary. In this study, we aimed to set up a selective solid phase extraction method using dummy molecularly imprinting approach for extraction and separation of hesperidin in lime juice to check the quality of commercial lime juice products of Mashhad city market. The imprinted polymers were synthesized by hesperitin as dummy template due to the hesperitin solubility in the wide range of porogenic solvents. The specificity extent of synthesized polymers toward hesperidin was tested and optimum one was used as adsorbent in solid‐phase extraction cartridge. The dummy molecularly imprinted polymer with high adsorption capacity for hesperidin (dissociation constant 0.12 μM) was successfully used for extraction and clean‐up of hesperidin in the lime juice matrix prior to analysis by high‐performance liquid chromatography. The analysis of hesperidin was done in the range of 0.312–50 μg/mL with detection limit of 0.05 μg/mL. This technique was successfully set up to remove the interfering compounds for analysis of hesperidin in commercial lime juice products.
