Uranium (VI) adsorption from aqueous solution by GO wrapped Cu/Fe bimetallic MOF composites

In this study, the thermodynamics and kinetics of U(VI) adsorption and removal on MIL-101(Fe, Cu)/GO from wastewater were studied. The effects of pH, contact time, initial concentration and adsorption temperature were systematically studied. The results showed an effective U(VI) adsorption capacity...

Description
Summary:In this study, the thermodynamics and kinetics of U(VI) adsorption and removal on MIL-101(Fe, Cu)/GO from wastewater were studied. The effects of pH, contact time, initial concentration and adsorption temperature were systematically studied. The results showed an effective U(VI) adsorption capacity of the MOF. The adsorption of U(VI) was analyzed by using different isotherms as well as various kinetics models. The results showed that Langmuir adsorption isotherm and quasi-second-order kinetic model were followed by the adsorption of U(VI) on MIL-101(Fe, Cu)/GO. Thermodynamic studies (Δ G
