In this research, the synthesize possibility of Potassium Nickel
Hexacyanoferrate complex on natural clinoptilolite, as a support for removal
of Cs+ and Sr+2 from radioactive waste, was investigated. Previous work
showed that in the high concentration of sodium ion the sorption of these
radionuclides on zeolites is low, therefore we enhance the efficiency for the
purpose with loading Potassium Nickel Hexacyanoferrate complex on
clinoptilolite. First Potassium Nickel Hexacyanoferrate complex was
synthesized and characterized using ICP-AES, XRD and SEM methods.
Then the structure of clinoptilolite and the complex loaded zeolite were
characterized using IR, EDS, SEM and XRD methods. Sorption of cesium
clinoptilolite and potassium nickel hexacyanoferrate-loaded clinoptilolite
(CFC) was determined in the presence of various concentration of sodium
ion. Results showed the sorption of CFC was improved in comparison to its
original natural clinoptilolite.
