Sustainable Cotton Dyeing in Nonaqueous Medium Applying Protic Ionic Liquids
(2017-10-02)
Dyeing processes are highly important for differentiation of textile products, and in general, they use a huge amount of water and chemical additives, generating a great environmental impact. In the last years, the interest ...
A química e toxicidade dos corantes de cabelo
(Sociedade Brasileira de Química, 2014-07-01)
The market for hair dye involves a growing range of products, which requires greater understanding of hair properties, mechanisms of action and color development. In this work, we present a critical analysis of the ...
Degradation of Acid Blue 40 dye solution and dye house wastewater from textile industry by photo-assisted electrochemical process
(Taylor & Francis IncPhiladelphiaEUA, 2007)
Assessment of by-products of chlorination and photoelectrocatalytic chlorination of an azo dye
(Elsevier B.V., 2012-02-29)
The present work describes a more efficient methodology for the chlorination of water containing disperse dyes, where the chlorinated byproducts identified by mass spectra are compared. this investigation, we tested the ...
Mutagenic activity removal of selected disperse dye by photoeletrocatalytic treatment
(SPRINGER, 2010)
The degradation of black dye commercial product (BDCP) composed of C.I. Disperse Blue 373, C.I. Disperse Orange 37, C.I. Disperse Violet 93 dyes was investigated by photoelectrocatalysis process. The dyes have shown high ...

Kinetic, isothermal, and thermodynamic models to evaluate acid blue 161 dye removal using industrial chitosan powder
(2018-03-01)
Textile dyes are often discarded into the environment. Most of them are toxic and their release leads to severe impacts. This study evaluated the potential of industrial chitosan powder as an adsorbent material capable of ...
Carbon Nanotube-Based Electrochemical Sensor for the Determination of Anthraquinone Hair Dyes in Wastewaters
(Mdpi, 2015-03-01)
The present work describes the development of a voltammetric sensor for the selective determination of Acid Green 25 (AG25) hair dye, widely used in commercial temporary hair dyes. The method is based on a glassy carbon ...
