MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202411072434 A) filed by Amity University, Noida, Uttar Pradesh, on Sept. 25, 2024, for 'an eco-friendly composite for efficient malachite green dye removal from wastewater and method thereof.'
Inventor(s) include Rachana Singh; Surbhi Sinha; and Aarushi Goya.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an eco-friendly composite material and method for the efficient removal of malachite green dye from wastewater. The composite is synthesized by chemically binding wood apple biochar 7 with microcrystalline cellulose using Fischer esterification and dehydration reactions, resulting in a material with high adsorption capacity. In experimental studies, 0.2 grams of the synthesized composite was introduced into a 25 ml solution containing 350 ppm of malachite green dye. The adsorption efficiency was monitored using a UV-Visible spectrophotometer, demonstrating a 99.96% reduction in dye concentration within 25 minutes at pH 9. The process is cost-effective, scalable, and 14 environmentally sustainable, offering a practical solution for treating dye contaminated wastewater. This invention addresses the limitations of traditional methods, providing a rapid and effective means for dye removal that is suitable for large-scale industrial applications."
