Synthesis, characterization, and caesium adsorbent application of trigonal zinc hexacyanoferrate (II) nanoparticles
Trigonal zinc hexacyanoferrate (TZHF) nanoparticle adsorbents for effective caesium ion (Cs+) removal were prepared using the chemical coprecipitation method. The morphologies of zinc hexacyanoferrate (ZHF) were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD)...
