Synthesis, characterization, and the effectiveness of cobalt hexacyanoferrate nanoparticles in Cs+ adsorbent application
Nanoscale cobalt hexacyanoferrate (CoHF) is a low-cost and a good selective adsorbent for cesium (Cs+) removal, which was prepared via a chemical coprecipitation method. Fourier transform infrared spectroscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and high-resolution transmission...

Nanoscale cobalt hexacyanoferrate (CoHF) is a low-cost and a good selective adsorbent for cesium (Cs+) removal, which was prepared via a chemical coprecipitation method. Fourier transform infrared spectroscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and high-resolution transmission electron microscopy images were obtained to determine the properties and morphologies of the CoHF. It is shown that the CoHF has a cubic structure (space group F-43m), and a Brunauer Emmett Teller surface area of 29.085 m2/g was demonstrated. The isothermal parameters of Cs+ adsorbed at temperatures from 298 to 348 Kelvin (K), according to the Langmuir isotherm model, the maximum value of absorption capacity was calculated to be 197.01 mg/g at 318 K. The Gibbs free energy change (ΔG°) has a negative value from − 37.93 to − 42.47 at different temperatures ranging from 298 to 348 K, indicating that cesium ion adsorption by CoHF is a spontaneous process and the adsorption rate increased with increasing temperature. The mechanism of Cs+ adsorption was examined for the first time by total reflection X-ray fluorescence analysis with a gallium internal standard. In addition, the primary mechanism of Cs+ adsorption through the ion exchange process was also proposed and discussed. |
