Abstract

The use of a coupling agent containing a mercapto, disulfide, tretrasulfide and/or polysulfide end group provides a mercury removal media having increased reactivity, stability, and mercury removal ability. The mercury removal media described herein is prepared by reacting an organophilic clay containing onium ions with a mercapto, disulfide, tetrasulfide, and/or polysulfide end moiety. Alternatively, the clay can be made organophilic by onium ion reaction prior to or simultaneously with the coupling reaction of the mercapto- or sulfide-end group-containing coupling agent.
