Arsenic (As), a highly toxic and carcinogenic heavy metal, poses significant risks to soil water quality, while oxytetracycline (OTC), widely used antibiotic, contributes environmental pollution due excessive human usage. Addressing the coexistence of multiple pollutants in environment, this study investigates simultaneous adsorption As(III) OTC using novel bimetallic zinc-iron-modified biochar (1Zn-1Fe-1SBC). The developed adsorbent demonstrates enhanced recovery, improved efficiency, cost-effective operation. Characterization results revealed high carbon-to-hydrogen ratio (C/H) specific surface area 1137 m2 g−1 for 1Zn-1Fe-1SBC. Isotherm modeling indicated maximum capacities 34.7 mg 172.4 OTC. Thermodynamic analysis confirmed that processes both were spontaneous (ΔG < 0), endothermic (ΔH > driven by chemical 80 kJ mol−1), with increased system disorder (ΔS 0). mechanisms involved interactions, including pore filling, hydrogen bonding, electrostatic attraction, complexation, π-π interactions. These findings underscore potential 1Zn-1Fe-1SBC as promising remediation wastewater containing coexisting pollutants.

To achieve high electrooxidation efficiency for phenol, this study explored the fabrication of Mn-MIL-100 catalysts at various calcination temperatures, loaded onto a carbon paper (CP) anode. The materials were characterized using scanning electron micros-copy, X-ray photoelectron spectroscopy, thermogravimetric analysis, and diffraction. Their electrocatalytic activities under temperatures evaluated through cyclic voltammetry (CV) tests, while effect pH in Mn-MOF modified CP electrodes on phenol degradation performance was investigated potentiostatic discharge method. Mn-MOF@CP calcined 400 °C 500 (denoted as Mn400@CP Mn500@CP, respectively) exhibited significantly enhanced current responses solution, attributed to an increase oxygen vacancy concentration. A 96.00 ± 1.53% achieved by within 16 h, it only 60.12 2.03% Mn500@CP 8.01 2.00% blank 4. Additionally, consistently demonstrated superior over across values. outstanding activity oxidation could be its lower charge transfer resistance. radical-mediated pathway proposed system, elucidating mechanism. These findings highlighted potential Mn-MOF-derived carbon-based organic contaminants.
