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 electrode modified with multiwalled carbon nanotubes activated in the presence of sulfuric acid, where the anthraquinone group present as a chromophore in the dye molecule is re...

The textile industry is one of the industries that generate a high volume of waste water. Approximately 10, 000 different dyes and pigments are manufactured worldwide with a total annual market of more than 7×10 metric tones per year (Ahluwalia and Goyal, 2007). In India textile is one of the oldest establishments with nearly 1569 large cotton textiles industries, which gives employment to near...

Silk yarns were dyed by using commercial basic, reactive and pre-metallised acid dyes. An aftertreatment with a commercial synthetic tanning agent (syntan) was applied to the dyeings and the aftertreated dyeings were further treated with metal salts in an attempt to improve wash fastness properties. When all samples (untreated, syntanned and syntanned/ backtanned speciments) were subjected five...

This work has studied the photoelectrochemical production of hydrogen peroxide and direct use produced material for degradation (decolorization) three common dyes: methylene blue, basic blue 41 acid orange 7. Hydrogen was in cathode compartment a photocatalytic fuel cell by atmospheric oxygen reduction. The operated with CdS-sensitized mesoporous titania photoanode simple carbon cloth carrying ...

In this study, the adsorption of certain water-soluble cationic dyes, (basic blue 9, basic blue 12, basic blue 17, brilliant cresyl blue, janus green B, basic green 4, basic violet 1, basic violet 3, and thionin) onto TriSyl silicas by batch adsorption at 25◦C was investigated. In the adsorption experiments, Langmuir type adsorption in the Giles classification system was found. Binding paramete...

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...

Compost from pine bark has been previously suggested as an effective low-cost biosorbent for different classes of textile dyes, although the existing studies have performed in non-competitive batch conditions, so effect competition or adsorption continuous-flow conditions not assessed. In this work, removal Basic Violet 10 (BV10) and Direct Blue 151 (DB151) by compost single bi-solute mixtures ...
