Abstract: | The adsorption of Congo red by multifunctional magnetic particles (designated as Fe3O4@NiSiO3) was studied. Kinetic and isotherm studies showed that the adsorption process followed the pseudo-second-order kinetic model and Freundlich model respectively. Thermodynamics studies showed that the adsorption process is spontaneous and endothermic in accordance with the physical adsorption principle. |
