Lanthanide sorbent based on magnetite nanoparticles functionalized with organophosphorus extractants Basualto Flores, Carlos; Gaete, José; Molina, Lorena; Valenzuela Lozano, Fernando; Yáñez Soto, Claudia; Marco, José F. (National Institute for Materials Science, 2015)In this work, an adsorbent was prepared based on the attachment of organophosphorus acid extractants, namely, D2EHPA, CYANEX 272, and CYANEX 301, to the surface of superparamagnetic magnetite (Fe3O4) nanoparticles. The ...
