Abstract : Polyamidoximes (pAMD) are known to have strong affinities for uranyl cations. Grafting
pAMD onto the surface of functionalized maghemite nanoparticles (MNP) leads
to a nanomaterial with high capacities in the extraction of uranium from wastewaters
by magnetic sedimentation. A diamidoxime (dAMD) specifically synthesized for this
purpose showed a strong affinity for uranyl: Ka = 105 M-1 as determined by Isothermal
Titration Calorimetry (nano-ITC). The dAMD was grafted onto the surface of
MNP and the obtained sorbent (MNP-dAMD) was characterized. The nanohybrids
were afterward incubated with different concentrations of uranyl and the solid phase
recovered by magnetic separation. This latter was characterized by zeta-potential
measurements, X-Ray Photoelectron Spectroscopy (XPS) and X-Ray Fluorescence
spectroscopy (XRF), whereas the supernatant was analyzed by Inductively Coupled
Plasma coupled to Mass Spectrometry (ICP-MS). All the data fitted the models of
Langmuir, Freundlich and Temkin isotherms very well. These isotherms allowed us
to evaluate the efficiency of the adsorption of uranium by MNP-dAMD. The saturation
sorption capacity (qmax) was determined. It indicates that MNP-dAMD is able
to extract up to 120 mg of uranium per gram of sorbent. Spherical aberration (Cs)-
corrected High-Resolution Scanning Transmission Electron Microscopy (HRSTEM)
confirmed these results and clearly showed that uranium is confined at the surface
of the sorbent. Thus, MNP-dAMD presents a strong potential for the extraction of
uranium from wastewaters
