Separation of copper ions by nanocomposites using adsorption process

Abstract In this research, a novel nanocomposite adsorbent, graphene oxide modified with magnetite nanoparticles and Lauric acid containing ethylenediaminetetraacetic acid (GFLE) has been applied for the eliminate of Cu2+ ions. Adsorption performance was considered as a function of solution pH, Cu2+...
