摘要： 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.
