Abstract

Green synthesis of magnetic gamma alumina nanoparticles (MGAl-NPs) for heavy metal adsorption: A novel approach for wastewater treatment. This study investigates the potential of magnetically modified gamma alumina nanoparticles (MGAl-NPs) for removing copper (II) ions from aqueous solutions. The synthesis of MGAl-NPs involves the mixture of aluminum hydroxide and magnetic iron oxide, resulting in a composite material with both magnetic and adsorptive properties. The adsorption capacity of MGAl-NPs was found to be 34.48 mg/g at optimal conditions of pH 5.0, initial concentration of 50 mg/L, and adsorbent dosage of 0.1 g.The adsorption kinetics followed the pseudo-second-order model, indicating that…
