      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 ...
    • 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 ...
    • In situ decolorization monitoring of textile dyes for an optimized UV-LED/TiO2 reactor 

      Tapia Tlatelpa, Tecilli; Trull Silvestre, José Francisco; Romeral Martínez, José Luis (2019-08-01)
      Article
      Open Access
      Heterogeneous photocatalysis, using photocatalysts in suspension to eliminate diverse contaminants, including textile wastewater, has several advantages. Nevertheless, current absorbance and decolorization measurements ...
    • 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 ...
    • Optoelectronic optimization of photocatalytic processes for wastewater treatment 

      Tapia Tlatelpa, Tecilli (Universitat Politècnica de Catalunya, 2019-10-03)
      Doctoral thesis
      Open Access
      Water pollution is an alarming problem that endangers the health of all living beings. The textile industry is listed as one of the most contaminating industries, since in order to carry out its dyeing and finishing ...
    • 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 ...
