Tóm tắt

In this investigation, the sorptive removal of Cesium ions (Cs+) from CsCl aqueous using Cu2[Fe(CN)6] nanoparticles was studied. The synthesis of Cu2[Fe(CN)6] nanoparticle was carried out, X-ray diffraction (XRD) was used to analyze the characteristics of Cu2[Fe(CN)6], and the total reflection X-ray fluorescence (TXRF) technique was applied to detect absorbent capacity. Some characteristics of Cu2[Fe(CN)6] including Miller indices (h,k,l), the spacing between the atomic planes (d), the lattice parameter (a), and volume of the unit cell (V) were calculated. All experiments in this research were studied at pH = 7 level and room temperature and change solute concentration. The Freundlich and the Langmuir isotherm model are applied to determine the heterogeneity factor (1/n) and the maximum adsorption capacity (qmax).
