Parametric Optimization of Ball-Milled Bimetallic Nanoadsorbents for the Effective Removal of Arsenic Species

Arsenic (As) removal from portable water bodies using the nanotechnology-based adsorption technique offers a unique method to lower As contamination below World Health Organization’s (WHO) maximum contaminant level (MCL). This work promotes systematic methodological-based study by optimizing different parameters that affect TiO2/γ-Fe2O3 nanocomposites (T/M NCs) prepared with green, facile, and cost-effective ball milling method. The studies X-ray Diffraction (XRD) illustrate structural modifications variations in constituting T/M ratios, high-resolution transmission electron microscopy (HRTEM) being used for NC morphological studies. optical characterization showed bandgap tuning between 2–2.8 eV reduced maghemite (γ-Fe2O3) content NCs elemental analysis confirmed desired stoichiometry of NCs. magnetic measurements interaction among particles tends towards exchange coupling behavior as weight ratio γ-Fe2O3 decreases most efficient an optimized condition (NC dose (8 g/L), contact time (15 min), concentration (2 ppm), pH (4)) resulted more than 99% species, suggesting excellent synthesized nanomaterial treatment making it economical other competing techniques materials.
