Removal of Dyes by the Process of Adsorption
2022Adsorption is one of the simplest ways and means to remove dyes from water. The process of adsorption simply involves the removal of water contaminants that come in contact with adsorbents, i.e., the materials of interest. The material should only have sufficient surface area, porosity, and adequate numbers of adsorption sites. Besides being one of the

Applications of Biosorption in Dyes Removal
2019Biosorption is a technique that has been widely studied for dye removal. Biosorption is, in general, the removal of a substance from aqueous solutions by biological materials and may include several mechanisms, such as ion exchange, adsorption, complexation and precipitation.

Removal of dyes and industrial dye wastes by magnesium chloride
Water Research, 2000Magnesium chloride, as compared to alum and polyaluminium chloride (PAC) is a less commonly used coagulant in the field of wastewater treatment, with a cost in between alum and PAC. It has been used in this study as a coagulant to investigate the eAectiveness in the chemical precipitation method for the removal of colouring matters.

Rapid urbanization and industrialization result in the discharge of harmful and toxic waste into the water bodies which are not easy to degrade thereby causing environmental pollution. Out of so many waste discharges, dye waste is noxious for aquatic life and for human as well; therefore, removal of these toxic compounds from water is one of the major ...

Waste Management, 1998
Adsorption techniques employing activated carbon have been found to be reasonably effective in the removal of some of the ionic impurities in water. However, economic considerations may require the use of inexpensive sorbents which are either naturally available or available as waste products from manufacturing processes. Slag is one such waste product

Removal of organic dyes by magnetic alginate beads
Water Research, 2008This study deals with the development of a clean and safe process for water pollution remediation. We have synthesized a magnetic adsorbent in order to develop a solid-phase extraction process assisted by a magnetic field. To follow an 'ecoconception' approach, magnetic beads containing magnetic nanoparticles and activated carbon are prepared with a ...

Removal of disperse dyes by the fungus Cunninghamella polymorpha
Journal of Bioscience and Bioengineering, 1999A disperse dye-removing fungus, Cunninghamella polymorpha, was isolated from soil. C. polymorpha efficiently removed an average 93% of 17 tested disperse dyes in 120 h, and 90% of C. I. Disperse Blue 60 was removed even at a high concentration of 500 mg/l. The dye removal was due to the sorption of dye to the fungal cells.

Biomimetic dynamic membrane for aquatic dye removal
Water Research, 2019This 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.

Microflora involved in textile dye waste removal
Journal of Basic Microbiology, 2003AbstractTextile 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.

Waste based chitosan membranes for dye removal
International Journal of Biological MacromoleculesWater 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+.
