Description
Summary:In exploration of an efficient and economical means for the treatment of radioactive wastewater, the performance of biopolymer/graphene oxide gels have been evaluated in the application for the separation of U(VI). The microscopic morphology and crystal structure of the obtained gels were analyzed by scanning electron microscopy, X-ray diffraction, Fourier transformed infrared spectra, and energy dispersive spectroscopy. The effects of adsorption factors such as solution pH and contact time were discussed to obtain the suitable process conditions. The experimental data were found to be agreed well with the Langmuri isotherm and the pseudo-second-order kinetic model.
