MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511116823 A) filed by Maharishi Markandeshwar, Ambala, Haryana, on Nov. 25, 2025, for 'selective aluminium sorption by crosslinked pectin beads.'
Inventor(s) include Sarvjeet Kaur; and Ashutosh S. Singh.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to Selective Aluminium Sorption by Crosslinked Pectin Beads. Old-style metal remediation methods often have limitations like high operational costs, incomplete metal removal, and generation of secondary pollutants. To get rid of these drawbacks, the invention provides a modified pectin material synthesized using ammonium persulfate (APS) as an initiator and N,N-methylene bisacrylamide (MBAAm) as a crosslinking agent to form a vigorous three-dimensional polymeric network. The resulting crosslinked pectin (pectin-cl-N,N-MBAAm) shows significantly higher swelling behaviour and a larger affinity for metal ions due to the abundance of carboxyl functional groups. The biosorbent demonstrates notable aluminium ion adsorption efficiency, achieving up to 60.32% removal at 55 C within 24 hours, thereby providing better result than conventional sorbents. The invention therefore offers a cost-effective, biodegradable, and sustainable solution for heavy-metal removal, with potential scalability for industrial wastewater treatment applications."
