  • TITANIA-BASED TREATMENT SOLUTION AND METHOD OF PROMOTING PRECIPITATION AND REMOVAL OF HEAVY METALS FROM AN AQUEOUS SOURCE
    Publication number: 20220227653
    Abstract: A treatment solution and method for removing heavy metal contaminants and oxyanion contaminants from an aqueous solution by promoting the affinity of precipitating the contaminants. The method adjusts the pH and the ORP of the contaminated aqueous solution by applying FeCl2 and/or NaOH reducing agents, and using and applying a titania-based treatment solution of TiO(SO4), H2SO4, and FeSO4.
    Type: Application
    Filed: April 5, 2022
    Publication date: July 21, 2022
    Inventors: James Knoll, Katie Henderson, Joshua L. Mertz
