    Abstract: Herein are described methods and materials for capturing mercury from, for example, the gases produced by the combustion of coal. The composition for the removal of mercury from the fluid includes a polysulfide selected from the group consisting of a calcium sulfide and a bromosulfide; the polysulfide supported by or carried on a surface of a silicate particulate. Disclosed methods include a process for manufacturing the bromosulfide or calcium-sulfide mercury-removal composition and a process of capturing mercury from a fluid, the process can include admixing a bromosulfide or calcium-sulfide mercury-removal composition and a fluid that includes mercury; wherein the bromosulfide mercury removal composition includes a bromosulfide supported by or carried on a surface of a silicate particulate; wherein the calcium-sulfide mercury-removal composition includes a calcium sulfide supported by or carried on a surface of a silicate particulate.

    Abstract: Herein is provided mercury sorbent compositions and methods for their manufacture. In embodiments, the mercury sorbent compositions can include calcium metal sulfides (CaxMySz), where M can be Cr, Mn, Fe, Co, Ni, Cu, Zn, or a mixture thereof where x can have a value from about 0.1 to about 5; where y can have a value of about 1, and where z can have a value of about 1 to about 10. In one example, the mercury sorbent composition can have the formula: Cax(Fe1-yCuy)Sz. In other embodiments, the mercury sorbent compositions can include copper sulfide carbonates (e.g., CuxSy(C03)z; wherein x can have a value from about 1 to about 5, y can have a value from about 1 to about 10, and z can have a value from about 0.1 to about 2.5. In one example, the mercury sorbent compositions can have the formula CuSx(CO3)y.
