The Prussian blue functionalized SiO₂ (nano-material of SiO₂-Fe-CN) was successfully prepared using a novel and simple preparation route. The SiO₂ nanoparticles were functionalized by amino group by refluxing with (3-Aminopropyl) trimethoxysilane, iron (III) immobilized the modified nanoparticles through interaction with the amino group, finally, SiO₂-Fe-CN nanomaterial produced as a result of potassium ferrocyanide addition. SEM, FTIR and XRD techniques were used for detecting the morphology, particle size, different functional groups and the crystal structure of the prepared nano-materials. The sorption potential of nano-material of SiO₂-Fe-CN towards cationic and anionic radioisotopes from aqueous and HNO₃ solutions were tested using carrier free method. The experimental results showed that nano-material of SiO₂-Fe-CN have high effective retention and recovery for ¹³⁴Cs, ⁶⁰Co and ⁹⁹Mo from nuclear liquid waste. Moreover, sorption of ⁹⁰Sr/⁹⁰Y is insignificant using SiO₂-Fe-CN nano adsorbent material. It is a promising and efficient nano adsorbent that could be used for upscaling design and application on liquid radioactive waste treatment facility.
