Hexavalent chromium (Cr(VI)) in wastewater poses serious environmental and ecological risks. A novel Fe3O4-loaded magnetic biochar (MBC) using Acacia falcata leaf powder was synthesized via one-step hydrothermal carbonization for efficient Cr(VI) removal. FESEM images revealed porous, irregular structures, EDS analysis confirmed Fe, O, C, Cr presence, validating adsorption. XRD indicated a lattice parameter of 0.8407 nm, characteristic magnetite nanoparticles, with an average crystallite size 11.29 nm. MBC exhibited superparamagnetic behavior facilitating easy separation. The deconvolution XPS spectra distinct peaks at 575.6 585.7 eV, corresponding to Cr(III), 577.3 587.8 Cr(VI), thereby confirming the dual roles reduction Batch adsorption followed pseudo-second-order Hill models, highlighting physisorption mechanisms.
