MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202641051246 A) filed by Mepco Schlenk Engineering College on April 22, 2026, for A Novel Bio-Adsorbent Derived From Acacia Auriculiformis Pods For The Removal Of Jakazol Orange Dye From Wastewater.
Inventors include Dr. Nayanathara O S; Ridhinaa S; and Tamilarasi M.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The present invention relates to the preparation and application of activated carbon synthesized from Acacia Auricidiformis pods for efficient removal ofjakazole dye from aqueous solution, one of the most commonly used dye in textile industry. The process involves washing, drying, grinding, chemical activation with sulfuric acid, and carbonization at 550°C to yield activated carbon with high surface area and well-developed porosity. Surface morphology analysis indicates enhanced pore development with increasing activation temperature. Batch adsorption studies demonstrated a complete color removal at the end of 45 min. The novelty of the invention lies in the use of Acacia auricidiformis pods as a precursor combined with optimized sulfuric acid activation and controlled pyrolysis to produce highly porous activated carbon for efficient dye removal. The invention offers the development of a novel, cost-effective, environmentally sustainable solution for color removal while simultaneously addressing the utilization of locally available material for activated carbon synthesis, providing an environmentally sustainable solution for dye- contaminated waste water treatment..
