In the study, the reduced graphene oxide/polyaniline (rGO/PANI) material was synthetically synthesized by in-situ polymerization of polyaniline (PANI) with reduced graphene oxide (rGO) for adsorption of Cr(VI) in simulated wastewater. The Cr(VI) adsorbed on the layer of rGO/PANI utilized as metal ion center, MIL-53(Cr)/rGO/PANI (M-53/G-P) and MIL-101(Cr)/rGO/PANI (M-101/G-P) composites were prepared by hydrothermal method. The prepared composite adsorbs Cr(VI) again, and the composites were characterized by XRD, XPS, BET, and FTIR before and after adsorption, and the adsorption mechanism was elucidated by XPS. Results indicate: compared with rGO/PANI (38.98 m2·g−1), the M-53/G-P (137.87 m2·g−1) and M-101/G-P (70.91 m2·g−1) show higher BET surface area. When pH is 2, initial concentration is 100 mg L−1 and dosage is 0,10 g (per 100 mL), the maximum adsorption capacities of M-53/G-P and M-101/G-P composite materials for Cr(VI) are 81.58 and 77.76 mg·g−1, respectively. The adsorption kinetics of Cr(VI) on the two composites conform to the pseudo-second-order kinetic model and the adsorption isotherm follows the Freundlich model. The adsorption mechanisms of Cr(VI) by the two materials involve electrostatic attraction, ion exchange, and complexation.

For aims of efficient BPA removal and breaking the limitations of conventional adsorption processes and adsorbents, amino-functionalized magnetic porous nanocomposites (NH2–MZFS) were synthesized via a modified Stöber sol–gel method, characterized and used to investigate behaviors of BPA adsorption. The results of characterization showed successful amino-functionalization and that the as-prepared nanocomposites with a regular morphology and mesoporous structure possessed a specific surface area of 121 m2 g−1 and saturation magnetization of 5.54 emu g−1. And the results of BPA adsorption indicated that the adsorption process reached the equilibrium of 28.25 mg g−1 in 30 min at 308 K, was best described by pseudo-second-order kinetic model and Langmuir isotherm model, and was spontaneous and exothermic in nature. Besides, the results of mechanism investigation depicted that, compared with the phenolic hydroxyl groups and benzene rings of BPA, hydroxyl groups and amino groups of NH2–MZFS participated in BPA adsorption with driving forces containing intermolecular hydrogen bonding, coordination, conjugation, electrostatic interaction and so on. In the constructed heterogeneous Fenton-like system, the used NH2–MZFS can be regenerated in-situ and reused with high regeneration efficiency of 72.73% after five runs. These findings suggest that NH2–MZFS could be a promising material for pollution treatment, and can provide a critical theoretical reference to the Bisphenols treatment and material application.</div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"32 1","pages":"313 - 329"},"PeriodicalIF":2.5,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
