Recovery of Nd3+ and Dy3+ from E-Waste Using Adsorbents from Spent Tyre Rubbers
Nogueira, Miguel; Matos, Inês; Bernardo, Maria; Pinto, Filomena; Fonseca, Isabel; Lapa, Nuno© 2024 by the authors Licensee MDPI, Basel, Switzerland.; This paper investigates the use of spent tyre rubber as a precursor for synthesising adsorbents to recover rare earth elements. Through pyrolysis and CO2 activation, tyre rubber is converted into porous carbonaceous materials with surface properties suited for rare earth element adsorption. The study also examines the efficiency of leaching rare earth el...

Maria Bernardo thanks FCT/MCTES for funding through program DL 57/2016—Norma transitória. Inês Matos thanks FCT/MCTES for contract CEECIND/004431/2022.; Rare earth elements (REEs), comprising seventeen metallic elements, including lanthanides, scandium, and yttrium, are indispensable for modern technological industries due to their unique properties. However, their su...
