INVESTIGATE THE ADSORPTION OF CESIUM ION (Cs+) AND STRONTIUM ION (Sr2+) ON Zn2[Fe(CN)6] NANOPARTICLES
Main Article Content
Abstract
Low-cost, nanoscale zinc hexacyanoferrate (ZnHF), an effective adsorbent for cesium (Cs+) and strontium (Sr2+) removal, was prepared using the chemical co-precipitation method. The Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS) spectra, and high-resolution transmission electron microscopy (HRTEM) images were performed to determine the morphologies of ZnHF. The Zn15[Fe(CN)6]12(2K).10H2O was the trigonal structure (space group p-3c1) in the range of 50-200 nm, the BET surface area 43.08 m2/g. The Cs+ and Sr2+ removal were dependent on pH; this material's maximum value of adsorption capacity (qmax) is achieved at a pH of 6. According to the Langmuir model qmax = 190.52 mg/g and 72.43 mg/g for Cs+ and Sr2+ respectively. The Langmuir model was conformable to describe the adsorption process of both Cs+ and Sr2+ ions by ZnHF. The low-cost easily synthesized nanoscale zinc hexacyanoferrate (ZnHF) material. This material becomes an attractive and promising adsorbent in treating Cs+ and Sr2+ ions of nuclear water.
