  • Combining electrochemistry and UV for the simultaneous wastewater decolorization and reduction of salinity 

    Gutiérrez Bouzán, María Carmen; Buscio Olivera, Valentina (2018-04-24)
    Article
    Open Access
    Textile dyeing processes with reactive dyes consume high amount of water and generate wastewater containing residual dyes and salts. In this work, wastewater generated by a textile industry was treated by means of ...
  • Comparison of different wastewater treatments for colour removal of reactive dye baths 

    López Grimau, Víctor; Vilaseca Vallvé, M. Mercedes; Gutiérrez Bouzán, María Carmen (2015-04-07)
    Article
    Open Access
    The generation of high-coloured wastewater is one of the main environmental problems of the textile industry. Reactive dyes are widely used in the dyeing of cellulosic fibres. However, they have low exhaustion degree ...
  • 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 ...
  • Microencapsulation of C.I. reactive orange 122 via solvent evaporation 

    Dutra, Fabio; Lis Arias, Manuel José; García Carmona, Óscar; García Carmona, Carlos; Souza Plath, Andre Mathias; Pereira Scachetti, Fabio Alexandre; Maesta Bezerra, Fabricio (2019)
    Conference report
    Open Access
    Microencapsulations protects the dye molecule from secondary reactions and release until contact with the fiber, triggered by stimuli. The procedure was performed using poly(lactic-acid-co-glycolic-acid), PLGA, and polyvinyl ...
  • Mineralization of hetero bi-functional reactive dye in aqueous solution by Fenton and photo-Fenton reactions 

    Torrades Carné, Francesc; García Hortal, José Antonio; García Montaño, Julia (2015-08-18)
    Article
    Open Access
    This study focused on the advanced oxidation of the hetero bi-functional reactive dye Sumifix Supra Yellow 3RF (CI Reactive Yellow 145) using dark Fenton and photo-Fenton conditions in a lab-scale experiment. A 2(3) factorial ...
  • Nanofiltración de colorantes reactivos para la reutilización del permeado 

    García Jiménez, María Gracia (Universitat Politècnica de Catalunya, 2014-06-27)
    Bachelor thesis
    Open Access
    Los procesos de tintura textil con colorantes reactivos generan grandes cantidades de efluente con color y con altas concentraciones de electrólito. En este proyecto se plantea el tratamiento de eliminación de color de ...
  • 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 ...
  • Photo-electrochemical treatment of reactive dyes in wastewater and reuse of the effluent: method optimization 

    Sala Gastón, Mireia; López Grimau, Víctor; Gutiérrez Bouzán, María Carmen (2014-11-01)
    Article
    Open Access
    In this work, the efficiency of a photo-electrochemical method to remove color in textile dyeing effluents is discussed. The decolorization of a synthetic effluent containing a bi-functional reactive dye was carried out ...
