Abstract:

In the present study, Fe₃O₄/graphene nanoparticles (Fe₃O₄/GN NPs) were obtained and modified with silane coupling agent. The effects of Cd (II) adsorption experimental parameters such as contact time and initial Cd (II) ion concentration, were investigated. The adsorption dynamics follow the laws of pseudo-second-order kinetics and the rate was controlled by chemical adsorption. The Langmuir isotherm model provided the better correlation between adsorbing capacity and equilibrium concentration.
