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 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 (ΔG < 0, ΔH < 0) demonstrated that the adsorption process is exothermic and spontaneous. The results revealed that MIL-101(Fe, Cu)/GO has a real prospect for the application in the adsorption and removal of U(VI).
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
