“…The reaction temperature had a significant effect on the adsorption capacity of MMCNT-SMIP, and 70 • C was found to be the suitable temperature. Since the initiator AIBN is temperature sensitive, the high temperature could increase the reaction rate, but too high would lead to its thermal decomposition [27]. The MMCNT-SMIP using DMF as porogen had better adsorption performance.…”

In this work, surface molecularly imprinted polymers based on magnetic multi‐walled carbon nanotubes were prepared for the specific recognition and adsorption of resveratrol. The functionalization of magnetic multi‐walled carbon nanotubes and the synthesis process of surface molecularly imprinted polymers were optimized. Characterizations were performed to demonstrate the successful synthesis of the imprinted materials. The imprinted materials showed satisfactory adsorption capacity of resveratrol (45.73 ± 1.72 mg/g) and excellent selectivity (imprinting factor 2.89 ± 0.15). In addition, the imprinted materials were used as adsorbents in molecularly imprinted solid‐phase extraction for the purification of resveratrol from crude extracts of some food and medicinal resources, achieving recoveries of 93.69%−95.53% with high purities of 88.37%−92.33%. Moreover, the purified products exhibited extremely strong free radical scavenging activity compared with crude extracts. Overall, this work provided a promising approach for the highly selective purification of resveratrol from natural resources, which would contribute to the application of this valuable compound in the food/nutraceutical fields.
