Abstract

In this study, hexacyanoferrate nanoparticle (NP) functionalised silica monoliths were used to selectively remove Cs⁺ from aqueous solutions which also contained large concentrations of Na⁺. Various NP loading levels were examined from 0.2 wt% up to 5.1 wt% producing different ¹³³Cs and ¹³⁷Cs sorption results.
