Cotton Fabric Coating by Cationic Starches to Aim for Salt‐Free Reactive Dyeing

ChemistrySelect, Volume 9, Issue 40, October 25, 2024.
Cationic starch is used as a coating pre‐treatment in cotton fabric reactive dyeing. Such cationised cellulose fabrics show comprehensive dye absorption which results in a substantive coloration without the addition of salt in the dye bath. Fabric property changes, fabric coloration, slightly decreased light and rub fastness and the fate of the ...

Adsorption of Remazol Black B dye on Activated Carbon Felt

Carbon: Science and Technology, 2008
The adsorption of Remazol Black B (anionic dye) on a microporous activated carbon felt is investigated from its aqueous solution. The surface chemistry of activated carbon is studied using X-ray microanalysis, "Boehm" titrations and pH of PZC measurements which indicates that the surface oxygenated groups are mainly acidic in nature.

Treatment of textile industry effluents with up‐flow anaerobic sulfidogenic reactor

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 8, Page 1921-1928, August 2024.
Abstract BACKGROUND Dyes present in textile wastewater can pose various environmental problems, including toxicity, carcinogenicity and mutagenicity, when released into receiving environments. Sulfidogenic bacteria play a crucial role in wastewater treatment by reducing sulfate and producing sulfide through the utilization of organic compounds in water.

Advances in Nanohybrid Membranes for Dye Reduction: A Comprehensive Review

Global Challenges, Volume 8, Issue 1, January 2024.
Nanohybrid membranes (NHMs) can be divided to two categories of photocatalytic and non‐photocatalysts. Hence, approximately 50% of NHMs are produced by Phase Inversion (PI) and most of NHMs are polymeric, the current paper will categorize NHMs according to these criteria.
