These research results belong to Zhong, Xin; Lu, Zhipeng; Liang, Wen; Hu, Baowei. Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde The article mentions the following:
The magnetic covalent organic framework with β-ketoenamine linkage (Fe3O4@COF(TpPa-1)) was fabricated by the hydrothermal method. The obtained Fe3O4@TpPa-1 integrated four advantages, namely easy preparation, high stability, excellent adsorption performance (485.2 m2/g) and good recoverability (19.5 emu/g), which enabled it an ideal sorbent for wastewater treatment. Fe3O4@TpPa-1 exhibited excellent adsorption capacities for Cr (VI) (245.45 mg/g) and bisphenol A (1220.97 mg/g). The adsorption kinetics and isotherms were in alignment to the pseudo-second-order and Langmuir model, resp. After five times cycles, the adsorption capacity of Fe3O4@TpPa-1 still retained at a high level. According to Materials Studio simulation and XPS anal., the adsorption mechanism was attributed to the presence of the homogeneously distributed imine and carbonyl functional groups in the framework of TpPa-1, allowing them to serve as platforms for anchoring heavy metals and organic pollutants. Besides, the hydrophobic skeleton structures of TpPa-1 endowed them good adsorption performance towards organic pollutants via hydrogen -bonding (NH…O…HO) and π-π interaction. Therefore, the recyclable Fe3O4@TpPa-1 showed a broad application prospects in environmental remediation. The results came from multiple reactions, including the reaction of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde)
