f-Block element separation mediated by carboxylated Fe3O4 nanoparticles as robust adsorbents in acidic systems

Characterization of CA-MNP

The absorption spectra of as-synthesized CA-MNP are shown in Fig. 1a the hump at 378 nm confirms the presence of the carboxylate. In contrast, the uplifting of the absorption spectra from the range of 600–450 nm…
