Fe3O4 Magnetic Biochar Derived from Pecan Nutshell for Arsenic Removal Performance Analysis Based on Fuzzy Decision Network

Year: 2025

Type: conference-paper

Abstract: This study evaluates Fe3O4 magnetic biochar synthesized from pecan nutshells for arsenic removal. Surface modification with Fe3O4 significantly enhanced arsenic adsorption selectivity and efficiency compared to raw biomass (PM). Synthesis variables (precursor type, particle size, Fe/precursor ratio, N2) and adsorption conditions (such as concentration, pH, agitation) were investigated. The modified biochar achieved >90% arsenic removal efficiency under various conditions, demonstrating the modification’s critical role. A fuzzy decision network was employed to analyze experimental results and identify optimal conditions for maximizing performance. This approach effectively leverages knowledge for scenario-specific optimization, offering a sustainable strategy for advanced water treatment materials.
