MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202611039684 A) filed by Galgotias University on March 30, 2026, for A Carboxymethyl Cellulose-Based Hydrogel Derived From Rice Straw For Efficient Removal Of Cationic Dyes From Aqueous Solutions.
Inventors include Dr. Rishabha Malviya; Aayush Prakash; and Dr. Sathvik Belagodu Sridhar.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present invention discloses a biodegradable hydrogel derived from rice straw-based carboxymethyl cellulose for the removal of cationic dyes from aqueous solutions. The hydrogel is synthesized through chemical modification of cellulose followed by crosslinking with acrylamide to form a three-dimensional polymeric network. The material exhibits high adsorption efficiency for methylene blue, governed by chemisorption mechanisms and supported by adsorption isotherm models. The hydrogel demonstrates excellent swelling behavior, thermal stability, and pH responsiveness. This invention provides a sustainable, low-cost, and eco- friendly solution for wastewater treatment while simultaneously utilizing agricultural waste, contributing to environmental protection and circular economy practices.
