Red mud is an industrial by-product produced in the process of alumina refining. It contains many iron elements, and traditional resource utilization method to extract it. This study took alternative approach by using red mud's content as substrate synthesize a novel iron-biochar adsorbent for removing heavy metals from wastewater. Walnut shell biochar was reacted with via in-situ reduction–oxidation produce iron-carbon composite (FexOy-BC). A series characterization analyses (e.g., SEM, FTIR, XPS, etc.) batch adsorption experiments were conducted investigate properties Cd(II) removal performance adsorbent, respectively. Response surface methodology further employed optimize conditions, identifying ideal 6 g/L dose, 10 mg/L initial concentration (C0), pH 6. The optimized quadratic model demonstrated excellent fit, average efficiency 92.59 % under optimal conditions. mechanism, renewability, preliminary cost-benefit analysis indicate that FexOy-BC has potential be highly efficient sustainable adsorbent. In summary, new can recover resources waste metal adsorbents, which comprehensively solves two long-standing problems waste.

This study demonstrated that catalyst support played a crucial role in tailoring the redox reactions of ferrate (Fe(VI)) with nanoconfined Cu, promoting production Cu(III) as highly reactive nonradical oxidant. The reactivity heterogeneous Fe(VI) activator (confined Cu–Mg; present primarily oxidation state +2), prepared by calcining mixtures Cu/Mg nitrates presence inorganic/organic supports, was substantially higher g-C3N4 metal nanoconfinement host than SiO2 and montmorillonite k10 (k10). structure Cu–Mg sites sensitive to type. Mg adhesive agent bridged Cu atoms graphitized carbon phase cause CuMg cluster formation unique g-C3N4, which enhanced metal–support interactions thus facilitated interfacial electron transfer from for selective formation. superiority Cu–Mg–C3N4/Fe(VI) organic at pH = 8 arose preferential based on UV–visible absorption situ Raman spectra, toward multiple organics, density functional theory-calculated energetics clusters Cu(II)-to-Cu(III) conversion. contrasts behaviors Cu–Mg–SiO2 Cu–Mg–k10 (accommodating separate phases) activation, initiated Fe(V)/Fe(IV)-induced main degradation route.
