Water & Wastewater Treatments, Drinking Water, Heavy Metal Removal, and Persistent Organic Pollutants (POPs) removal.
Inventors have developed a range of zeolites having surface modifications with graphene oxide, reduced graphene oxide (rGo), and sulfide for removal of persistent organic pollutant (POPs) and targeted heavy metals from water supply. Highly microporous three-dimensional structure of zeolite offers exceptional ion-exchange and sorption properties advantageous in range of heavy metals removal from water. The adsorption capacity of the zeolite is evaluated based on functionalized surface, dosage, contact time and pH levels in water. Furthermore, acid treated and functionalized zeolite with graphene oxide (GO) have shown efficient removal of persistent organic pollutants (POPs) comprising of BPA, PFOA, Metformin, Atrazine etc., from water. This technology utilizes highly favorable synergistic effects between zeolite and the graphene oxide for significantly enhanced removal of POPs in water to improve the quality and safety of treated water resources.
