Investigation and optimization of the performance of sono-photo-electro-Fenton process for removal of Acid Black 172 and Disperse Blue 56 from polluted water: comparison of the degradation activity with electro-Fenton-based processes
(2021-04-15)
Article
Accés restringit per política de l'editorialThis study investigates the decolorization of two widely used textile dyes (Acid Black 172 (AB172) and Disperse Blue 56 (DB56) by using a combined sono-photo-electro-Fenton (SPEF) process. The effects of dye structure and ... -
Journal of Materials Chemistry C
(Royal Society of Chemistry, 2013-03-28)
Article
Accés obertThe structure of the meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS4) J-aggregates could be determined by X-ray and electron diffraction methods. A sheet-like architecture reveals the relationship between structure and ... -

Treball Final de Grau
Accés restringit per decisió de l'autorEn aquest projecte es va estudiar la descoloració i la mineralització de banys de tintura residuals amb un colorant reactiu mitjançant tractament electrolític aprofitant la presència del clorur sòlid utilitzat en la tintura. ... -
Orange-derived and lemon-derived adsorbents with controlled grain for an efficient elimination of some cationic and anionic dyes
(2021-09-22)
Article
Accés obertPurpose: This study aims to demonstrate that orange-derived and lemon-derived systems can be used in continuous processes as efficient adsorbents to the entrapment of some anionic and cationic dyes in the textile dyeing ... -
Removal of aromatic amines and decolourisation of azo dye baths by electrochemical treatment
(2013-03-17)
Article
Accés restringit per política de l'editorialThe presence of aromatic amines in effluent from dyeing processes of the textile industry is an added problem to the high coloration typical of this type of effluent. The main objective of the present work was to eliminate ... -
Study of a process based on salt-free dyeing of cellulosic fibres
(Universitat Politècnica de Catalunya, 2019-10)
Treball Final de Grau
Accés obertIndustrial application of conventional dyes onto cellulose fibres requires a high amount of salt which has a negative impact on environmental ecology. In order to overcome this problem the purpose of the project is to find ...
