Concentration and Isolation of Radiocesium from Reactor Water Using Titanium Hexacyanoferrate

Abstract

Titanium hexacyanoferrate was applied for isolation of cesium, as well as zirconium, niobium and ruthenium radionuclides from water reactor coolant. High sorption efficiency was obtained: more than 99% for cesium, more than 90% for zirconium and niobium and about 70% for ruthenium. Mechanism of sorption and elution for these ions is discussed.
