Thermal Decomposition of Potassium Titanium Hexacyanoferrate(II) Loaded with Cesium in a Fixed Bed Calciner

Highly efficient removal of 137Cs in seawater by potassium titanium ferrocyanide functionalized magnetic microspheres with multilayer core–shell structure

“…The (200) (220) and (420) reections of TiFe(CN) 6 $2H 2 O phase were clearly observed, which matches well with a previous study. 36 Meanwhile, an evident strong resonance at 2090 cm À1 is observed in the FT-IR spectrum of Fe 3 O 4 @SiO 2 @KTiFC (Fig. 3d), which is the characteristic stretching vibration of cyanide groups, conrming the successful deposition of potassium titanium ferrocyanide on the surface of the Fe 3 O 4 @SiO 2 microspheres.…”
