GirdlerSulfide
The Girdler sulfide process, often referred to as the GS process, is an industrial water treatment method used to remove dissolved radium-226 and other trace metals from water streams. It relies on the controlled precipitation of metal sulfides by introducing sulfide-forming agents, producing insoluble solids that can be separated from the liquid.
Developed in the mid-20th century for applications in the nuclear materials and mining industries, the GS process
The core principle involves forming metal sulfides through the addition of sulfide ions under carefully regulated
Operational considerations include the use of hydrogen sulfide or other sulfide donors, corrosion-resistant equipment, and robust
In modern practice, the GS process has been largely superseded in many settings by ion exchange and
