Alcaraz Romo, Lorena ; García Díaz, Irene ; González, Laura ; Rabanal, María Eugenia ; Urbieta Quiroga, Ana Irene ; Fernández, Paloma ; López, Félix A. | Elsevier Science BV | 2019-06Several phases with variable stoichiometry ZnxMn3-xO4 (with x = 0.25, 0.85 and 1) and ZnO have been obtained from the black mass, a widely generated residue of wasted alkaline batteries. The obtained samples have been characterized by X-ray diff[...]texto impreso
Alcaraz, Lorena ; Urbieta Quiroga, Ana Irene ; Fernández Sánchez, Paloma ; López, Félix A. | Elsevier | 2020-04Two electric-arc furnace flue dusts, a waste generated during the steel production process, were characterized and their photocatalytic activity was assessed. Chemical composition by X-ray fluorescence (XRF) analysis identified that both dusts w[...]texto impreso
Rodríguez, Olga ; Alguacil, Francisco J. ; Escudero Baquero, Esther ; García Díaz, Irene ; Fernández Sánchez, Paloma ; Sotillo Buzarra, Belén ; López, Félix A. | Royal Society of Chemistry | 2020-06-07The slag from the extraction processes of metals from their ores may contain valuable components that, if adequately recovered, can be reintroduced in the technological life cycle. This is the case for the material obtained in Penouta mines in t[...]texto impreso
López, Félix A. ; Cebriano Ramírez, Teresa ; García Díaz, Irene ; Fernández Sánchez, Paloma ; Rodríguez, Olga ; Lopez Fernandez, Ana | Elsevier Ltd. | 2017-04-01Two different precursors of zinc oxide were prepared via the ammoniacal ammonium carbonate leaching of the black mass obtained during the recycling of alkaline batteries. For a concentration of 0.1 mol/L of ammonium in the leaching solution, zin[...]
