  • Acid leaching of LiCoO2 enhanced by reducing agent. Model formulation and validation. 

    Cerrillo-Gonzalez, Maria del Mar; Villen-Guzman, Maria; Vereda-Alonso, Carlos; Rodriguez-Maroto, Jose Miguel; Paz-Garcia, Juan Manuel (Elsevier, 2021-08-25)
    In this work, a model has been formulated to describe the complex process of LiCoO2 leaching through the participation of competing reactions in acid media including the effect of H2O2 as reducing agent. The model presented ...
  • Chemical reduction of nitrate by zero-valent iron: Shrinking-Core versus Surface Kinetics Models 

    Villen-Guzman, Maria; Paz-Garcia, J.M.; Arhoun, B.; Cerrillo-González, María del Mar; Rodriguez-Maroto, Jose Miguel; [et al.] (MDPI, 2020-02-12)
    Zero valent iron (ZVI) is being used in permeable reactive barriers (PRB) for the removal of oxidant contaminants, from nitrate to chlorinated organics. A sound design of these barriers requires a good understanding of ...
  • Recovery of Li and Co from LiCoO2 via Hydrometallurgical–Electrodialytic Treatment 

    Cerrillo-Gonzalez, Maria del Mar; Villen-Guzman, Maria; Vereda-Alonso, Carlos; Gomez-Lahoz, Cesar; Rodriguez-Maroto, Jose Miguel; [et al.] (MDPI, 2020-03-27)
    Lithium-ion batteries play an important role in our modern society as the main option to power portable electronic devices and electric vehicles. The growing demand for these batteries encourages the development of more ...
  • Hydrometallurgical extraction of Li and Co from LiCoO2 particles–Experimental and Modeling 

    Cerrillo-González, María del Mar; Villen-Guzman, Maria; Acedo-Bueno, Luis Fernando; Rodriguez-Maroto, Jose Miguel; Paz-Garcia, J.M. (MDPI, 2020-09-13)
    The use of lithium-ion batteries as energy storage in portable electronics and electric vehicles is increasing rapidly, which involves the consequent increase of battery waste. Hence, the development of reusing and recycling ...
  • Sequential extraction procedure: a versatile tool for environmental research 

    Villen-Guzman, Maria; Cerrillo-González, María del Mar; Paz-Garcia, Juan Manuel; Vereda-Alonso, Carlos; Gomez-Lahoz, Cesar; [et al.] (CISA publisher, 2020-12-28)
    The sequential extraction procedure as a tool to assess the environmental risk of metals in solid matrices has been widely studied. In this work, other promising application of these methods is proposed: the evaluation of ...
  • Modeling of Electrokinetic Remediation Combining Local Chemical Equilibrium and Chemical Reaction Kinetics 

    Masi, Matteo; Paz-Garcia, J.M.; Gomez-Lahoz, Cesar; Villen-Guzman, M.D.; Ceccarini, Alessio; [et al.] (2020-02-24)
    A mathematical model for reactive-transport processes in porous media is presented. The modeled system includes diffusion, electromigration and electroosmosis as the most relevant transport mechanism and water electrolysis ...
  • Activation of electrospun lignin-based carbon fibers and their performance as self-standing supercapacitor electrodes 

    Ruiz-Rosas, Ramiro; Cordero, Tomás; Rodriguez-Mirasol, Jose; Rosas, Juana María; García-Mateos, Francisco José; [et al.] (2020-02-17)
    The production and activation of self-standing carbon electrodes from electrospun lignin fibers was analyzed in this work. Carbon microfibers were prepared at 900 °C from air-stabilized spun cloths by direct carbonization ...
  • Electrodialytic processes in solid matrices. New insights into batteries recycling. A review. 

    Villen-Guzman, Maria; Arhoun, Brahim; Vereda-Alonso, Carlos; Gomez-Lahoz, Cesar; Rodriguez-Maroto, Jose Miguel; [et al.] (2019-02-26)
    Electrodialytic Remediation has been widely applied to the recovery of different contaminants from numerous solid matrices solving emerging issues of environmental concern. Results and conclusions reported in studies about ...
