Functionalized nanomaterials with surface-active groups have garnered significant research interest due to their wide-ranging applications, particularly in water treatment for removing various contaminants. This study focuses on developing a novel, multi-functional nanobiosorbent by synthesizing nanosized biochar from artichoke leaves (NBAL) and molybdic acid (MA). The resulting nanobiosorbent, MA@NBAL, is produced through microwave-irradiation process, offering promising material enhanced environmental remediation. characteristics of assembled MA@NBAL were evaluated SEM-EDX, XPS, TGA, FT-IR, zeta potential detection. size particles ranged 18.7 23.7 nm. At the same time, EDX analysis denoted existence several major elements related percentage values carbon (52.9%), oxygen (27.6%), molybdenum (8.8%), nitrogen (4.5%) nanobiosorbent. effectiveness Hg(II) ions was monitored via batch method. optimized maximum removal capacity onto established at pH 6.0, 30.0 min equilibrium 20 mg providing 1444.25 mg/g 10.0 mmol/L concentration Hg(II).

Chromium exists from both natural geological processes and human actions, it has a substantial impact on health ecosystems. This study addresses the major challenges in using biochar as an environmentally friendly, sustainable, economical sorbent for removing chromium hexavalent throughout remediation process. The results exhibited that produced non-woody feedstocks pyrolyzed at (300°C −700°C) significantly large amount of various functional groups, higher pH (7 to 11.10) CEC (27 21.70 cmol kg−1), greater surface area (2–300 m2g−1), O/C H/C ratios with increasing carbonization temperature, adsorption capacities (1.63 435 mg g) superior performance removal compared biochars woody-biomass. use equilibrium isotherm, thermodynamic, kinetic models aids comprehending interactions between biochar, well their processes.
