Green construction of eco-friendly hydrophilic porous teamed boronate affinity hydrogels for highly specific separation of naringin under physiological pH
Green, high efficient and sustainable management of secondary high-value resources such as agricultural waste has significant economically, scientific and environmentally beneficial value for the future human development, but it remains a serious challenge. Some tasks persist in industrial-scale continuous separation processes while simultaneously optimizing sorbents structure and separation efficiency. Herein, a novel green eco-friendly porous boronate affinity hydrogels (AOO-PAM@CNCs-DB) were fabricated based on Pickering emulsion microreactors for the specific enrichment of flavoniods. In the emulsion system, the Artemisia argyi oil (AAO) is one of the main natural component of Artemisia, which acts as oil phase can effectively reduce the environmental pollution in the emulsion polymerization process. In addition, the emulsion stabilized particles with B-N recognizing sites based on cellulose nanocrystals (CNCs-DB) acts as specific recognition unit and physical sacrificial cross-linking network, which significantly enhancing the mechanical properties and accurate recognizing efficiency in real coarse samples. Benefiting the advantages of teamed boronate affinity, the AOO-PAM@CNCs-DB hydrogels possessed excellent recognition capabilities and rapid mass transfer at the physiological conditions. The maximum adsorption capacity of AOO-PAM@CNCs-DB hydrogels towards NRG were up to 51.54 μmol g −1 . Further, the AOO-PAM@CNCs-DB hydrogels had excellent selective performance and reusability, and the enrichment performance decreased by 8.27 % after 6 cycles. Meanwhile, the AOO-PAM@CNCs-DB hydrogels can be effectively extracted and enriched NRG with a purity of 92.47 %. This work provides a simple and reliable basis for the preparation of multifunctional hydrogels and holds promise for practical application in the treatment of agricultural wastewater containing flavoniods.
