VARANASI NEWS - IIT (BHU) and Parul University Develop Green Technology to Remove Toxic Dye from Wastewater

Khabarilaal News Desk:

Researchers from Indian Institute of Technology (BHU) Varanasi and Parul University have jointly developed an innovative green technology to remove malachite green, a highly toxic and carcinogenic dye, from industrial wastewater—marking a major breakthrough in sustainable environmental research.

Innovative nanocomposite developed using orange peel waste

The research team developed a novel SnO₂/PANI-Co-PPy nanocomposite using orange peel extract (Citrus sinensis) as a natural reducing agent. This makes the technology waste-derived, environmentally friendly, and highly sustainable.

Removes 97% toxic dye in just 30 minutes

The newly developed material demonstrated an impressive 97.06% removal efficiency of malachite green within just 30 minutes, with a remarkable adsorption capacity of 1250 mg g⁻¹.

Affordable and scalable for industrial use

One of the major advantages of this technology is that it requires no expensive equipment, hazardous chemicals, or specialised labour, making it cost-effective and easily scalable for industrial wastewater treatment.

Published in prestigious scientific journal

The research findings were published in the renowned Royal Society of Chemistry journal RSC Advances under the title: “Adsorption of Malachite Green from Aqueous Solutions Using a Novel SnO₂/PANI-Co-PPy Nanocomposite.”

Director IIT (BHU) congratulates research team

Amit Patra praised the researchers, stating that such collaborative work reflects the institute’s commitment to solving major environmental challenges through sustainable innovation.

Future focus on regeneration and real-world applications

The research team confirmed that future studies will focus on regeneration and reuse of the adsorbent material and its application in real-world multi-component industrial wastewater systems.
