MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202411095458 A) filed by Lovely Professional University on December 04, 2024, for Graphene-Oxide Coated Filters For High-Efficiency Heavy Metal Removal In Industrial Waste Streams.
Inventors include Prasann Kumar; Mastu Patel; and Polu Picheswara Rao.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: The invention relates to graphene-oxide-coated filters designed for the efficient removal of heavy metals from industrial wastewater. The filter consists of a porous substrate, such as ceramic or polymer, coated with graphene oxide, which possesses functional groups that effectively adsorb heavy metal ions like lead, cadmium, mercury, and arsenic. The filter offers high removal efficiency, achieving over 90% adsorption of contaminants even at trace levels. It operates across varying pH and salinity conditions, making it adaptable for diverse industrial applications. Additionally, the filter is regenerative, allowing multiple reuse cycles through low-energy processes like electric fields or mild acid rinsing. This technology provides an environmentally sustainable, cost-effective solution for treating industrial effluents and ensuring compliance with environmental regulations.
