Investigating the Efficiency of Wastewater Treatment Plant Sludge in Removing Azo Dye Reactive Red 195 from Synthetic Wastewater in Aerobic and Anaerobic Conditions [PDF]

Journal of Mazandaran University of Medical Sciences
Background and purpose: Azo dyes are present in the wastewater of most textile factories, and if they enter water resources, they pose risks to the health of humans and the living environment due to the effects of toxicity, biological accumulation, and ...

Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

Journal of Applied Polymer Science, Volume 143, Issue 33, September 5, 2026.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.

Isolation and screening of azo dye decolorizing bacterial isolates from dye-contaminated textile wastewater

Soil & Environment, 2011
Azo dyes are released into wastewater streams without any pretreatment and pollute water and soilenvironments. To prevent contamination of our vulnerable resources, removal of these dye pollutants is of greatimportance.

Textile Effluent Containing Azo Dyes Eco-Friendly Bioremediation using Lentinus sp. in a Packed-Bed Bioreactor with Pine Sawdust as an Organic Inducer

Universitas Scientiarum
Industrial textile effluents containing azo dyes pose a major environmental challenge due to their persistence and toxicity. This study evaluated the capacity of a native white-rot fungus (Lentinus sp.) to treat a real textile effluent polluted with an ...

Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 3996-4006, August 2026.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Occurrence and Washout of Health‐Hazardous Chemicals in Children's Clothing

Contact Dermatitis, Volume 95, Issue 2, Page 148-158, August 2026.
A survey of 60 children's garments from the Swedish market showed a varying, often highly complex chemical content. The highest levels were generally found in synthetic materials and the lowest in light‐coloured cotton. Further, the washout effect by laundry and sweat migration of textile chemicals was investigated.

Dietary impact of shrimp diets containing a mixture of nucleotides, β‐glucan, and mannan oligosaccharides on the growth performance, innate immunity, gene expression, and histology

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract This experiment investigated the impact of Hilyses, a fermented Saccharomyces cerevisiae‐based supplement containing bioactive nucleotides, β‐glucans, and mannan oligosaccharides (MOS), on the performance and physiology of whiteleg shrimp, Litopenaeus vannamei (initial weight 4.47 ± 0.07 g).
