Abstract: Abstract Environmental radionuclides’ contaminations have attracted widespread concerns owing to their austere hazardousness in physicochemical and accumulative bio-toxicities. Herein, magnetic carboxymethyl-β-cyclodextrin coated iron oxides nanoparticles (CM-CD-MNPs) were successfully fabricated using the chemical co-precipitation approach. The…
