Abstract
Synthesis of a support material impregnated with silver sulfide provides a sorbent composition. Generating the silver sulfide relies on reaction of sulfur dioxide and one of hydrogen gas and hydrogen sulfide in presence of the support material following silver loading of the support material. Contacting a fluid stream with the sorbent composition removes heavy metal from the fluid stream.
