摘要

The precipitation process was successfully employed to prepare ZnFe2O4 and ZnFe2O4@SiO2 nanoparticles. The synthesized nanoadsorbents were characterized employing transmission electron microscopy (TEM), X-ray diffraction (XRD), and Brauner-Emmett and Teller (BET) methods. The potential adsorption capacities of the generated nanoparticles were assessed under various conditions, including pH, starting dye concentration, contact time, and temperature. The adsorption efficiency of ZnFe2O4@SiO2 nanoparticles (95
