Abstract:

Some of the radiochemistry experiments in some universities are relatively outdated and involve insufficient experimentation times. This paper describes the design of a new radiochemistry experiment. Using chitosan as a raw material, an anion exchange resin was synthesized by a two-step reaction. Its structure and micromorphology were characterized by infrared spectroscopy (IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). Using this material, the adsorption properties of U in an alkaline solution were studied. The designed experiment is easy to conduct and allows students to prepare their own materials; this is challenging and can stimulate students' interest in learning, as well as cultivate in them the art of systematic scientific research thinking and environmental awareness.

Key words: Comprehensive radiochemistry experiment, Anion exchange resin, Functionalized chitosan, Adsorption of U
