Abstract

This study employed in situ electrochemical synthesis of copper-zinc ferrocyanide (CuZnFC) to effectively remove Cs⁺ from simulated liquid radioactive wastes (LRWs). Through single-factor experiments, the optimal reaction conditions were established as follows: an initial pH of 8.0, a molar ratio of [Fe(CN)₆]^4- to Cs⁺ of 10:1, a reaction temperature of 25 °C, a current density of 6 mA·cm⁻², and a stirring rate of 400 r·min⁻¹, achieving a Cs⁺ removal rate of 99.978 %. The precipitate analysis revealed its composition as CuZn[Fe(CN)₆]·6.18H₂O, which exhibited a cubic crystal structure and rapidly absorbed Cs⁺ from the simulated liquid radioactive wastes.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
