Simultaneous removal and separate recovery of radioactive Cs⁺ and I^- ions from wastewater using a reusable bifunctional composite, Ni@Pt/K₂NiFe(CN)₆.

ABSTRACT: Radioactive Cs⁺ and I^- ions are major components of nuclear wastewater, typically existing as counter ions. Due to their high water solubility and mobility, these ions can spread through contaminated water and soil into ecosystems, necessitating continuous removal and management. In this study, we synthesized a reusable bifunctional Ni@Pt/K₂NiFe(CN)₆ composite that can simultaneously remove radioactive Cs⁺ and I^- ions and, for the first time, enable their separate recovery in aqueous solutions. In this material, K₂NiFe(CN)₆ acted as an electrochemically switched ion exchanger, controlling the adsorption/desorption of Cs⁺, while Pt enabled the spontaneous adsorption and electrochemical desorpt
