Abstract
A composition for selectively removing a first ionic contaminant from a wastewater stream. The composition is formed into a particle. The composition includes a core formed of a non-active material relative to the first ionic contaminant, and, a shell formed from an active material relative to the first ionic contaminant, wherein the active material comprises between 10 to 50 wt % of the particle. The shell may also include a binder material that may be non-active relative to the first ionic contaminant, but active relative to a second ionic contaminant. The core may be formed from a glass-forming material so that a vitrification process may be used for the spent solid waste.
