      Article
      Accés obert
      Manganese–Aluminum powders were recently reported to show high efficiency and fast reaction rates as decolorization materials for azo-dye aqueous solutions. This work presents a detailed study of different aspects of this ...

    • Dealloying of Cu-Mg-Ca alloys 

      Mbarek Wael, Ben; Pineda Soler, Eloi; Escoda, Lluïsa; Suñol Martinez, Juan Jose; Khitouni, Mohamed (Multidisciplinary Digital Publishing Institute (MDPI), 2018-11-08)
      Article
      Accés obert
      The chemical dealloying of Cu-Mg-Ca alloys in free corrosion conditions was investigated for different alloy compositions and different leaching solutions. For some of the precursor alloys, a continuous, pure fcc copper ...

    • Degradation of azo dyes by rapidly solidified metallic particles 

      Mbarek Wael, Ben; Pineda Soler, Eloi; Khitouni, Mohamed; Fiol Santalo, Núria; Escoda, Lluïsa; Suñol Martinez, Juan Jose (2015)
      Comunicació de congrés
      Accés obert
      Azo compounds are one of the most common families of dyes used in textile and leather treatments. An important step during the treatment of water polluted by these compounds, is the degradation of the compounds by ...

    • Effects of the Addition of Fe, Co on the azo dye degradation ability of Mn-Al mechanically alloyed powders 

      Mbarek Wael, Ben; Saurina Canals, Joan; Escoda, Lluïsa; Pineda Soler, Eloi; Khitouni, Mohamed; Suñol, Joan Josep (Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-25)
      Article
      Accés obert
      Azo compounds are used in the textile and leather industry. A significant step during the azo dyes treatment of water is the degradation by breaking the N=N bonds. This break produces the decolorization of water. In this ...
