Untreated synthetic dye effluents severely threaten aquatic ecosystems by blocking sunlight, depleting dissolved oxygen and releasing compounds with potential ecological toxicity. Among the various ...

Dyes like Congo red and methyl orange create brightly hued shirts, sweaters and dresses. But these commonly used azo dyes can be toxic, carcinogenic and are hard to remove from wastewater. David Chem, ...

David Chem, a Ph.D. candidate in chemical engineering at the University of Arkansas, has created an eco-friendly method for eliminating azo dyes by utilizing a typical byproduct from the pulp and ...

The novel process involves creating metallic ‘clusters’ of just nine gold (Au) atoms chemically ‘anchored’ to titanium dioxide which in turn drives the reaction by converting the energy of absorbed UV ...

IIT Guwahati researchers found a bacterium that degraded 98.5% of toxic textile dye, offering a greener approach to textile wastewater treatment.

The study found a novel bacterium that can break down 98.5% of a widely used textile dye, offering a safer wastewater ...

Indian Institute of Technology Guwahati and BHU researchers have pioneered an eco-friendly biological method using a novel bacterium to effectively degrade toxic azo dyes in textile wastewater, ...

Guwahati, Sept 16: Researchers at the Indian Institute of Technology-Guwahati (IIT-G) have developed an eco-friendly biological approach to treat textile wastewater containing toxic azo dyes.

Researchers at Australia’s Flinders University have discovered a way to degrade and potentially remove toxic organic chemicals, including azo dyes, from wastewater using a chemical photocatalysis ...

David Chem, chemical engineering graduate student, holds on the right a vial of water with methyl orange dye. On the left, the water is clear after modified lignin bonds with the dye and falls to the ...
