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 ...

(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 ...
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 ...
Uso de liposomas industriales en la tintura de la lana a nivel de planta piloto, usando colorantes del tipo complejo metálico 1:2. (Instituto de Investigación Textil y Cooperación Industrial, 1998-07)
Open AccessSe ha investigado la aplicación de una suspensión de liposomas de tipo comercial de fosfatidilcolina de tamaño definido (aproximadamente de 100 nm) como transportador del colorante azoico de complejo metálico 1:2 "Lanaset ...
