The novelty of this Thesis comes from the development of a simple procedure to completely transform a hazardous aluminum waste into added-value materials of great industrial interest, as zeolites, which are used later as adsorbents for the removal of heavy metals and ammonium from aqueous effluents. There are not previous works related to the use of the hazardous aluminum waste as a raw material for the synthesis of zeolites. In this work the following stages were developed: i) Characterization of different aluminum wastes to get a representative sample. ii) Lab-scale hydrothermal synthesis and characterization of zeolites from aluminum waste to define the optimal experimental conditions. iii) Scaling up of the process (bench-scale synthesis) to assess its industrial application. iv) Development of a more sustainable synthesis process by alkaline effluents recycling in order to achieve a zero waste and zero effluents process. v) Using the zeolites as adsorbents for the removal of heavy metals and ammonium to decontaminate water. Aluminum waste, due to its high aluminum content (Al2O3 ~ 66 wt.%), was characterized and used as the only aluminum raw material for the lab- and bench-scale synthesis of zeolites in the Na2O-Al2O3-SiO2-H2O system. The synthesized zeolites exhibited high cation exchange capacities (CEC) and suitable adsorption properties, resulting in potential adsorbents for the removal of heavy metals and ammonium from aqueous solutions.Peer reviewedUniversidad Carlos III de MadridConsejo Superior de Investigaciones Científicas (España)López Delgado, AuroraLópez Andrés, SolConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201820182018info:eu-repo/semantics/doctoralThesishttp://purl.org/coar/resource_type/c_db06http://hdl.handle.net/10261/173003reponame:DIGITAL.CSIC.
