    Sala, Mireia; López Grimau, Víctor; Gutiérrez Bouzán, María Carmen (2016-03-18)
    Article
    Accés obert
    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 ...
  • Application of PVDF ultrafiltration membranes to treat and reuse textile wastewater 

    Buscio Olivera, Valentina; Crespi Rosell, Martin; Gutiérrez Bouzán, María Carmen (2016)
    Article
    Accés restringit per política de l'editorial
    In this work, the feasibility of polyvinylidene difluoride ultrafiltration membranes to treat textile wastewater was studied. The C.I. Disperse Orange 30 and C.I. Disperse Rubine 73 were selected as pollutant for the ...
  • Study of the presence of geosmin in bottled mineral water by CLSA and GC-MS

    Article
    Accés obert
    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 ...
  • Photocatalytic membrane reactor for the removal of C.I. Disperse Red 73 

    Buscio Olivera, Valentina; Brosillon, Stephan; Mendret, Julie; Crespi Rosell, Martin; Gutiérrez Bouzán, María Carmen (2015-06-01)
    Article
    Accés obert
    After the dyeing process, part of the dyes used to color textile materials are not fixed into the substrate and are discharged into wastewater as residual dyes. In this study, a heterogeneous photocatalytic process combined ...
  • Relevance of toxicity assessment in wastewater treatments: case study-four fenton processes applied to the mineralization of C.I. Acid Red 14 

    Idel Aouad, Rajaa; Valiente, Manuel; Gutiérrez Bouzán, María Carmen; Vilaseca Vallvé, M. Mercedes; Yaacoubi, Abdirani; Tanouti, Boumediene; López Mesas, Montserrat (2015-01-01)
