Abstract
Abstract
AlBaNi-LDH nanoparticles have been synthesized by the co-precipitation method. A series of characterization analyses (Scanning Electron Microscope, Energy Dispersive X-ray, Transmission Electron Microscope, X-ray Diffraction, Atomic Force Microscope, and Infrared spectroscopy) proved that the surface structure of AlBaNi-LDH nano-particles was the key mechanism for UO2
2+ adsorption. The synthesized product showed good performance in UO2
2+ adsorption efficiency in neutral pH with a maximal adsorption capacity of 137 mg/g. The results demonstrated the adsorption process fitted well with pseudo-second-order and Langmuir isotherm models. Also, the effects of coexisting ions and different eluents are briefly described. These results confirm that AlBaNi-LDH is an effective material for the adsorption of UO2
2+ from an aqueous solution with reusable availability.
