Magnetic nanoparticle CuFe2O4 showed
adsorption capacity of 51.02, 42.02, and 40.16 mg/g for Nd(III),
La(III), and Ce(III), respectively (Tu & Johnston, 2018). Marwani et
al. (2018) synthesized CeO2-CdO nanomaterial and used it
for adsorption of Y(III) from a solution containing Co(II), Cu(II),
Cr(III), Cr(VI), Pb(II), W(VI), Y(III) and Zn(II). The distribution
coefficient (Kd) for Y(III) reported was 17,743.90 ml/g
with a capacity (qm) of 84.67 mg/g. Other nano
adsorbents, nano-thorium (IV) oxide, and nano-zirconium oxide showed
adsorption capacities of 10.5 mg/g and 18.0 mg/g for Y (III),
respectively (Dubey & Grandhi, 2019). High adsorption capacities of
1111 for La(III) and 1000 mg/g for Ce(III) were obtained at pH 5 with
transition metal oxide (TMO) nanowires synthesized via hydrothermal
processing of a metal mix (Co, Fe, Ni) followed by pyrolysis (Sarmadi et
al., 2021).
