Abstract:
Radioactive cesium ions (Cs+) pose a serious threat to ecosystems and human health because of their long half-life and high toxicity, making the development of efficient removal technologies imperative. Among available methods, metal hexacyanoferrate (MHCF)-based adsorption is a highly promising approach for Cs+ removal due to its high selectivity and low operating costs. In recent years, extensive research has been conducted on the design and fabrication of MHCF-based composite adsorbents and the optimization of adsorption processes, leading to significant advancements. This review summarizes recent synthesis strategies for such composite adsorbents targeting Cs+ removal, systematically classifies different substrate materials, and discusses their structural and functional characteristics as well as adsorption principles and performance features. It also analyzes the characteristics and mechanisms of various separation processes (such as membrane adsorption and electrochemical adsorption) in enhancing mass transfer efficiency and achieving adsorbent regeneration. Furthermore, the adsorption/desorption mechanisms and related experimental and theoretical research methods are elucidated. Finally, the review points out that current research in this field still faces challenges in terms of material stability, process integration, and practical applications, and provides an outlook on future development prospects.
