Abstract:

Coprecipitation of microamounts of Cs with ferrocyanides of various metals, exhibiting a high sorption activity with respect to Cs ions, was studied. The distribution coefficients of ¹¹⁷Cs were determined in coprecipitation with the ferrocyanides in 0.1 M NaNO₃. The precipitated ferrocyanide was separated from solution by filtration through a Trumem metal-ceramic membrane. Cesium is recovered most efficiently with ferrocyanides of bivalent transition metals (Ni, Co, Cu, Fe, Cd).
