In situ electrochemical synthesis of copper-zinc ferrocyanide for removal of cesium in simulated liquid radioactive wastes
This study employed in situ electrochemical synthesis of copper-zinc ferrocyanide (CuZnFC) to effectively remove Cs<sup>+</sup> 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)<sub>6</sub>]<sup>4-</sup> to Cs<sup>+</sup> of 10:1, a reaction temperature of 25 °C, a current density of 6 mA·cm<sup>-2</sup>, and a stirring rate of 400 r·min<sup>-1</sup>, achieving a Cs<sup>+</sup> removal rate of 99.978 %. The precipitate analysis revealed its composition as CuZn[Fe(CN)<sub>6</sub>]·6.18H<sub>2</sub>O, which exhibited a cubic crystal structure and rapidly absorbed Cs<sup>+</sup> from the simulated liquid radioactive wastes.
