Sánchez-Hernández, Ruth ; Padilla, Isabel ; López Andrés, Sol ; López Delgado, Aurora | Hindawi Publishing Corporation | 2018This work evaluates the use of a synthetic NaP1 zeolite obtained from a hazardous Al-containing waste for the removal of ammonium (NH4+) from aqueous solutions by batch experiments. Experimental parameters, such as pH (6–8), contact time (1–360?[...]texto impreso
Jiménez, Jose A. ; Padilla, Isabel ; López Delgado, Aurora ; Fillali, Laila ; López Andrés, Sol | Wiley | 2015-01Boehmite synthesized through a sol?gel route from a nonconventional raw material, as an aluminum waste, was calcined at temperatures between 500 and 1500°C. Quantification of crystalline phases was performed by the Rietveld refinement of the XRD[...]texto impreso
Sanchez Hernández, Ruth ; Padilla, Isabel ; López Andrés, Sol ; López Delgado, Aurora | Elsevier | 2017-09The feasibility of developing an eco-friendly bench-scale zeolitization process of NaP1 from an Alcontaining waste and under recycling of effluents was evaluated.Prior lab-scale tests were performed to optimize the synthesis conditions. The mixt[...]texto impreso
Sanchez Hernández, Ruth ; López Delgado, Aurora ; Padilla, Isabel ; Galindo Llorach, Roberto ; López de Andrés, Sol | Elsevier | 2016NaP1, SOD, and ANA zeolites were synthesized from a hazardous aluminum waste as main aluminosilicate source by a one-step hydrothermal synthesis. This allowed the total transformation of the waste and no other solid residues were produced. The c[...]texto impreso
Sánchez-Hernández, Ruth ; Padilla, Isabel ; López Andrés, María del Sol ; López-Delgado, Aurora | Taylor & Francis | 2018-09The removal of Pb2+, Cd2+, and Hg2+, which act as endocrine disruptors, from aqueous solutions was performed using a NaP1-type zeolite synthesized from a hazardous aluminum waste. The effects of parameters such as pH, contact time, adsorbent dos[...]texto impreso
Padilla, Isabel ; López Delgado, Aurora ; López Andrés, Sol ; Álvarez Aguirre, Marta ; Galindo Llorach, Roberto ; Vázquez Vaamonde, Alfonso J. | Hindawi Publishing Corporation | 2014-01The aim of this paper is to evaluate the feasibility of obtaining alumina from boehmite using a free, clean, and unlimited power source as the solar energy. Boehmite was obtained by hydrothermal treatment of a hazardous waste coming from aluminu[...]texto impreso
López Delgado, Aurora ; Robla Villalba, José Ignacio ; Padilla, Isabel ; López Andrés, Sol ; Romero, Maximina | Elsevier | 2020-05A potential route to minimize the environmental impact of industrial activities is, among other approaches, the use of hazardous wastes as less-common raw materials for the preparation of other materials. Realistic technologies for waste managem[...]
