Nuclear energy has become an important part of energy structure for our country, however, it is still a big challenge to settle the problems of radioactive wastewater. Layered double hydroxides(LDHs) is a kind of anionic clay materials, which have been attracted much attention in the treatment of radionuclide-containing wastewater due to its controllable composition, adjustable anionic types, large specific surface area, tunable particle size and morphology. In this paper, we mainly focused on the adsorption behavior and mechanism of LDHs for radioactive wastewater. Besides, several key challenges in using LDHs as sorbents for capture of radioactive ions are presented. We hope that this work could shed light on the sustainable development of LDHs as amendment for radioactive wastewater in future.

Key words: Layered double hydroxides(LDHs), Stratified structure, Radionuclide, Adsorption
