20.500.12556/DiRROS-24947 Green synthesis of a magnetite/graphitic carbon nitride 2D nanocomposite for efficient ▫$Hg^{2+}$▫ remediation Novel nanoadsorbents demonstrate the potential to efficiently eliminate harmful substances, such as Hg2+, from the environment while preserving ecological balance. However, the search for environmentally-friendly nanomaterials as ideal adsorbents, as well as the development of suitable synthesis protocols, remains a challenge. This study presents an effective thermal-sonication technique for producing unique de novo tris-s-triazine carbon nitride nanosheets decorated with magnetite nanoparticles (M-g-CN). The structural integrity and chemical properties of the M-g-CN nanocomposite were extensively characterized using a battery of analytical instruments, including FTIR, SEM, TEM, XRD, XPS, AFM, Raman, and NMR. The obtained data, along with the analysis results, are discussed in detail. The novel synthesis method yields a high percentage (97.7%) of stable, highly selective, and reusable M-g-CN (40 mg mL−1). The resulting M-g-CN effectively binds Hg2+, with binding efficiencies of 96.0%, 97.5%, 98.2%, and 99.4% for Hg2+ concentrations of 50 pg mL−1 in marine, stream, precipitation, and ultra-pure matrices, respectively. Also, the magnetite-decorated particles can be easily retrieved using an applied magnetic field. This greener and scalable synthesis method does not require harsh chemicals, making it cost-effective, eco-friendly, and non-toxic compared to other technologies such as carbon filters, ion exchange resins, chemical precipitation, membrane filtration, electrochemical methods, and biological remediation. Overall, the synthesized M-g-CN exhibits wide-ranging potential applications, particularly as a green adsorbent in passive samplers or materials for remediation purposes. mercury elimination nanoadsorbents nanocomposites živo srebro odstranjevanje nanokompoziti true false true The Royal Society of Chemistry Združeno kraljestvo Angleški jezik Slovenski jezik This journal is © The Royal Society of Chemistry 2023 Neznano 2026-01-05 11:48:55 2026-01-05 11:48:56 2026-01-06 03:43:48 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Soavtorji iz Slovenije: Jan Gačnik, Igor Živković, Sreekanth Vijayakumaran Nair, Nigel Van de Velde, Alenka Vesel, Primož Šket, Ivan Jerman, Milena Horvat; Opis vira z dne 23. 8. 2023; str. 2658-2671 iss. 10 Vol. 10 Oct. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-06-07 2023-06-30 2023-07-01 620.3 2051-8161 10.1039/D3EN00367A 162041091 https://pubs.rsc.org/en/content/articlelanding/2023/EN/D3EN00367A 1 25c6b3fa-ea24-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37368 RAZ_Chouhan_Raghuraj_S._2023.pdf RAZ_Chouhan_Raghuraj_S._2023.pdf 1 49E691EBBF6D10F384BAF4D64D15D6ED e4bd237a5211084438eb66e18930252bf4ae7ad38a145af1e6a6c509bf0a379e 8e4d697d-ea24-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37369 Institut Jožef Stefan 0 0 0
