| Abstract: | As global energy demand grows and carbon neutrality goals advance, nuclear energy poses significant challenges to public health and ecological safety due to the radioactive liquid waste generated by its large-scale application. Traditional methods for treating radioactive liquid waste, such as chemical precipitation and evaporation concentration, are hindered by high risks of secondary pollution, substantial energy consumption, and poor selectivity. Adsorption methods, known for their high efficiency, low energy consumption, and operational simplicity, have emerged as a major research focus for radionuclide removal. This paper systematically reviews the research progress in adsorption technologies for radioactive liquid waste treatment, focusing on the adsorption performance, mechanisms, and application potential of five material categories: organic adsorbents, inorganic adsorbents, metal-based materials, composite adsorbents, and biosorbents. These materials exhibit distinct characteristics in terms of specific surface area, functional group design, and structural stability. However, challenges remain, including unclear competitive adsorption mechanisms in complex high-salinity aquatic environments and insufficient long-term irradiation stability. This paper addresses these issues by outlining development paths for adsorbent materials in controllable synthesis, mechanistic insight, and engineering applications, thereby providing a theoretical foundation and technical reference for the safe disposal of radioactive liquid waste.
