- Abstract
The use of uranium as a fuel in the nuclear energy industry has also led to an increase in mining. For this reason, there is an increase in the rate of uranium mixed into the waters. On the other hand, one of the most important problems of nuclear energy is spent fuel waste that creates radioactive pollution. Radioactive uranium and its compounds cause serious damage to the human body, kidney failure and death. Removal of uranium from water by adsorption is among the subjects that are actively studied by many research groups in terms of not posing a threat to living health. While various sorbents find their place in adsorption processes with their different potentials, hydrogel-based adsorbents stand out thanks to their swelling properties, expandable functional structures and biodegradable forms. Adsorption on hydrogel materials is due to the ionizable functional groups of the monomers in its structure. In this review, the adsorption process of uranium, which is a radioactive pollutant, was examined in terms of pseudo-first-order, pseudo-second-order, Elovich and intraparticle diffusion kinetic models, and widely used Langmuir and Freundlich isotherm models, current studies on its removal with chitosan and alginate-based biocomposite sorbents were presented.
