Dye removal by immobilised fungi

Biotechnology Advances, 2009
Dyes are widely used within the food, pharmaceutical, cosmetic, printing, textile and leather industries. This has resulted in the discharge of highly coloured effluents that affect water transparency and gas solubility in water bodies. Furthermore, they pose a problem because of their carcinogenicity and toxicity.

Dye removal by laccase-functionalized micromotors

Applied Materials Today, 2021
Abstract Laccase-based poly(3,4-ethylenedioxythiophene)-polypyrrole/Pt (PEDOT-PPy-COOH/Pt) micromotors were electrosynthesized, characterized and applied for the decolorization of azo dyes widely used in the textile industry and found in textile wastewater.

Dye Removal from Textile Dye Wastewater Using Recycled Alum Sludge

Water Research, 2001
The removal of dyes from textile dying wastewater by recycled alum sludge (RAS) generated by the coagulation process itself was studied and optimized. One hydrophobic and one hydrophilic dye were used as probes to examine the performance of this process. It was found that RAS is a good way of removing hydrophobic dye in wastewater, while simultaneously

Microflora involved in textile dye waste removal

Journal of Basic Microbiology, 2003
AbstractTextile dyes are heavily used in factories for coloring different cloth materials. This work was designed to identify microorganisms capable of removing textile dyes, either by biodegradation or by biosorption.We expected to isolate microorganisms adapted to high dye concentrations from sites near textile industry complex.

Ceramic Nanocomposite Membranes for Dye Removal

2021
Due to their complex aromatic molecular structure, dyes persist in the aquatic environment and pose severe environmental and human health risks. To reduce the risks, it is important to treat dye-contaminated wastewater before it is discharged into waterways. A number of treatment methods have been used for dye removal from wastewater.

Biomimetic dynamic membrane for aquatic dye removal

Water Research, 2019
This study utilized physical adsorption and filtration of carbon nanotubes (CNTs) and laccases to fabricate biomimetic dynamic membrane (BDM) for the advanced treatment of dye wastewater. In BDM, the adsorption, enzymatic degradation and membrane separation demonstrated a synergism effect on pollutant removal.

Dye Removal Using Microbial Biosorbents

2018
Due to the rapid urbanization and industrialization, huge amounts of toxic sludge are being disposed into the environment. Improper management of this toxic sludge contaminates all components of the environment. Dyes are being used from very ancient period of time as colouring substances for almost every commodity.

Removal of dyes by agricultural waste

Sustainable Chemistry and Pharmacy, 2020
Abstract Biowaste is an important sustainable source of adsorption activities for many harmful materials, such as hazardous metals/elements and organics. It has many advantages over the conventional materials due to its low cost, abundance, affective adsorption capacity, and recyclability.

Lignin-Based Membrane for Dye Removal

2021
Urbanization, industrial activities, and the rapid increase in major pollutants have led to serious environmental concerns. Dye wastewaters are poor degradable and toxic compounds with serious damage for the life. The demand for a clean environment for pollutants such as dyes has increased.

Waste based chitosan membranes for dye removal

International Journal of Biological Macromolecules
Water contamination is an important global issue. This study explores dye removal potential of chitosan-based membranes with lemon waste and Cu2+, selected based on circular economy and green chemistry. Lemon waste and chitosan were used to recover Cu2+.
