  • Silver recovery as Agnanoparticles from ion-exchange regenerant solution
    Patent number: 10807085
    Abstract: Silver is recovered as Ag0 nanoparticles from the spent solution obtained from the regeneration of an Ag-loaded ion exchange resin using electrolysis. The reclaimed regenerant solution is recycled and reused in a closed-loop scheme over multiple cycles. The recovered Ag0 nanoparticles are monodisperse, spherical in shape, and have a mean diameter of about 6 nm.
    Type: Grant
    Filed: November 16, 2018
    Date of Patent: October 20, 2020
    Assignee: University of Massachusetts
    Inventors: Tabish Nawaz, Sukalyan Sengupta, Chen-Lu Yang
