Covenantee: Ecole des mines d'AlèsAzo 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 (Universitat Politècnica de Catalunya, 2017-07-06)
Open AccessAzo 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 ...
Open AccessHeterogeneous photocatalysis, using photocatalysts in suspension to eliminate diverse contaminants, including textile wastewater, has several advantages. Nevertheless, current absorbance and decolorization measurements ...
(Desalination publications, 2018-12-01)
Open AccessIn 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 ...
(Universitat Politècnica de Catalunya, 2019-10-03)
Open AccessWater 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 (2016-03-18)
Open AccessAn 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 ...
Restricted access - publisher's policyConsiderable 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 ...
