Keywords:Geological disposal, Layered double hydroxide, Anion adsorbent

In order to improve the retardation performance of radionuclide migration in geological disposal, the basic adsorption characteristics of in-house produced LDH were evaluated. The results show that Co-Fe LDH has high adsorption performance for Se(IV) and Mo(VI).
