研制了六氰合铁酸铜（CuHCFIII）纳米粒子膜，并将其涂敷在轧制的片状电极上，用于柱分离废水中的铯。结果表明，切换正负极电位可以实现Cs的吸附与解吸平衡。XPS和等温线研究表明，电化学氧化还原的Fe（II/III）的CuHCFIII膜的单层作出贡献的可逆Cs分离。最大限度地减少二次废物，简单的再生和均匀涂层的任何大小，建议一个有前途的柱技术从实际废水中顺序去除铯。
Nanoparticle film of copper hexacyanoferrate (CuHCFIII) was developed and coated on the rolled sheet electrodes for column cesium separation from wastewater. Results indicated well balance of Cs adsorption and desorption can be achieved switching the potentials between anodes and cathodes. XPS and isotherm studies indicated the electrochemical oxidation-reduction of Fe(II/III) on the monolayer of the CuHCFIII film made contributions to reversible Cs separation. Minimization of secondary waste, simple regeneration and uniformly coating for any size, suggest a promising column technology for sequential removal of Cs from actual wastewater.
