      Azo dyes are often found in the environment as a result of their wide industrial uses. These industrial pollutants are common contaminants in wastewater and are difficult to decolourise due to their complex aromatic ...
    • Ceramic-supported graphene oxide membrane bioreactor for the anaerobic decolorization of azo dyes 

      Amin, Mohammad Shaiful Alam; Stüber, Frank Erich; Giralt Marcé, Jaume; Fortuny Sanromá, Agustín; Fabregat Llagostera, Azael; Font Capafons, Josep (2021-12-22)
      Article
      Open Access
      A continuous compact membrane bioreactor consisted of ceramic-supported graphene oxide membrane (CSGoM) was implemented for the first time for anaerobic biodecolorization of monoazo Acid Orange 7 (AO7), diazo Reactive Black ...
    • Comparative anaerobic decolorization of AZO dyes by carbon-based membrane bioreactor 

      Amin, Mohammad Shaiful Alam; Stüber, Frank Erich; Giralt Marcé, Jaume; Fortuny Sanromá, Agustín; Fabregat Llagostera, Azael; Font Capafons, Josep (2021-04-02)
      Article
      Open Access
      This study used a novel integrated technology of ceramic supported carbon membrane(CSCM) to degrade azo dyes through an anaerobic mixed culture. The CSCM worked simultaneouslyas biofilm support, redox mediator, and nano-filter ...
    • Degradación de contaminantes provenientes de la industria textil mediante partículas metálicas de aleaciones Al-Ca 

      Martinez Alvarez, Gabriel (Universitat Politècnica de Catalunya, 2017-07-06)
      Bachelor thesis
      Open Access
      Azo dyes are synthetic organic compounds that are difficult to degrade and also dangerous because of their carcinogenic and mutagenic potential. The use of metallic particles for degrading azo dyes is a big opportunity ...
    • Fenton coupled with nanoflitration for elimination of tartrazine 

      Escalona, I.; Stüber, Frank Erich; Fortuny Sanromá, Agustín; Bengoa, Christophe José; Fabregat Llangotera, Azael; Font Capafons, Josep (2012)

    • Kinetic models for the electrochemical decolouration of two reactive azo dyes 

      López Grimau, Víctor; Pepió Viñals, Montserrat; Gutiérrez Bouzán, María Carmen; Buscio Olivera, Valentina (Desalination publications, 2018-12-01)
      Article
      Open Access
      In this work, the indirect oxidation of two azo dyes (Colour Index Reactive Orange 4 and 13) was performed in an electrochemical batch cell in the presence of chloride as an electrolyte. The effect of different operational ...
    • Photoassisted electrochemical treatment of azo and phtalocyanine reactive dyes in the presence of surfactants 

      Sala, Mireia; López Grimau, Víctor; Gutiérrez Bouzán, María Carmen (2016-03-18)
      Article
      Open Access
      An electrochemical treatment (EC) was applied at different intensities to degrade the chromophoric groups of dyes C.I. Reactive Black 5 (RB5) and C.I. Reactive Blue 7 (Rb7) until uncolored species were obtained. Decolorization ...
    • Texture-modified activated carbons as catalysts in biodecolourisation of azo dyes 

      Mezohegyi, Gergo; Gonçalves, Filomena; Órfao, José J.M.; Bengoa, Christophe José; Stüber, Frank Erich; Font Capafons, Josep; Fortuny Sanromá, Agustín; Fabregat Llangotera, Azael (2009)
      Conference lecture
      Restricted access - publisher's policy
      Considerable attention has been focused on the reduction of azo dyes discharged from dyeing, textile and other industries since some of them or their metabolites may cause toxicity. The efficient treatment of these ...
    • Uso de liposomas industriales en la tintura de la lana a nivel de planta piloto, usando colorantes del tipo complejo metálico 1:2.
