Adsorption Studies on the Removal of Anionic and Cationic Dyes from Aqueous Solutions Using Discarded Masks and Lignin

Molecules, 2023
The carbon materials derived from discarded masks and lignin are used as adsorbent to remove two types of reactive dyes present in textile wastewater: anionic and cationic.

Removal of Reactive Anionic Dyes from Binary Solutions by Adsorption onto Quaternized Kenaf Core Fiber

International Journal of Chemical Engineering, 2017
The most challenging mission in wastewater treatment plants is the removal of anionic dyes, because they are water-soluble and produce very shining colours in the water.

Effect of dye structure and redox mediators on anaerobic azo and anthraquinone dye reduction

Química Nova, 2012
We investigated the biological decolourisation of dyes with different molecular structures. The kinetic constant values (k1) achieved with azo dye Reactive Red 120 were 7.6 and 10.1 times higher in the presence of RM (redox mediators) AQDS and riboflavin,

NOVEL REACTIVE RED DYES

AUTEX Research Journal, 2003
Abstract Dyes with two monochlorotriazine or with two monochlorotriazine and two vinylsulphone reactive groups have been investigated for establishing an enhancement of the dyeability of cotton fabrics. The effect of the diamine bridge linking two chromophore systems on the degree of dye exhaustion from the dyebath and dye bonding with ...
