摘要： A liquid suspension comprised of ferrous sulfide particles and method of using the same for the removal of selenium from industrial gas. Said liquid suspension may be (1) directly injected, or (2) coated onto or into a substrate and then injected into an industrial gas containing selenium to remove said selenium from the industrial gas stream in a dry scrubber system. Said liquid suspension of ferrous sulfide particles may also be used to remove selenium contained in industrial gases in a wet scrubber system.

摘要： A method of reducing the mobility of metal contaminates in mediums such as soil, groundwater, sludge, etc. that involves contacting the mediums with a reagent that is a ferrous sulfide suspension that contains at least FeS and Al(OH)3. The reagent is produced by reacting a solution that contains at least NaAlO2 and NaOH with a solution that contains FeCl2, HCl and water to form a reaction mixture that contains Fe2+, Cl−, Na+, Al(OH)3 and H2O; and adding NaHS to the reaction mixture. The mobility of the metal contaminates is reduce by adsorption of the metal contaminates in the medium onto the surface of ferrous sulfide or Al(OH)3 in the ferrous sulfide suspension; adsorption of the metal contaminates in the medium onto iron (hydr)-oxides formed in the suspension; and precipitation of the metal contaminates.

摘要： A method of treating, stabilizing, precipitating, or otherwise removing heavy metal ions contained in a contaminated media, which method includes: providing a sodium-iron-sulfide mineral or crystalline phase, either alone or in combination with a pH adjusting substance; contacting said contaminated media containing heavy metal ions with the sodium-iron-sulfide mineral or crystalline phase, either alone or in combination with a pH adjusting substance; and allowing the contaminated media containing the heavy metal ions to react with said sodium-iron-sulfide mineral or crystalline phase, either alone or in combination with a pH adjusting substance, such that the contaminated media containing heavy metal ions form single or mixed metal-sulfide precipitates or co-precipitates.

摘要： A wet gas scrubber liquor and method of using the same to remove mercury from flue gases. The wet gas scrubber liquid is an alkaline liquid suspension of ferrous sulfide particles that can be prepared by combining together a ferrous ion source such as ferrous chloride, a sulfide ion source such as sodium hydrosulfide and an alkalinity source such as sodium hydroxide. When used to scrub flue gases to remove mercury from flue gases the mercury reacts with said alkaline liquid suspension of ferrous sulfide particles and can be removed by at least one of: i) adsorption onto said ferrous sulfide particles; ii) adsorption onto iron (hydr)-oxides that form in said alkaline liquid suspension of ferrous sulfide particles; and iii) absorption by reacting with sulfur formed in alkaline liquid suspension of ferrous sulfide particles and forming mercuric sulfide as a precipitate.
