Abstract: Various aspects of the present invention pertain to methods of sorption of various materials from an environment, including radioactive elements, chlorates, perchlorates, organohalogens, and combinations thereof. Such methods generally include associating graphene oxides with the environment. This in turn leads to the sorption of the materials to the graphene oxides. In some embodiments, the methods of the present invention also include a step of separating the graphene oxides from the environment after the sorption of the materials to the graphene oxides. More specific aspects of the present invention pertain to methods of sorption of radionuclides (such as actinides) from a solution by associating graphene oxides with the solution and optionally separating the graphene oxides from the solution after the sorption.

Abstract: Systems are disclosed for making and using micro-porous particulates at least partially composed of metal sulfides, particularly alkaline earth metal and transition metal sulfides, as sorbents for removal of mercury from flue gas. Calcium sulfide micro-porous powders derived from the high temperature reduction of calcium sulfate and calcium sulfite are disclosed to be reactive substrates for a group of sorbents for adsorption of mercury from coal combustion flue gases produced by the utilities industry, as well as from natural gas and gaseous and liquid hydrocarbons. The sorbents are useful for cost-effectively adsorbing elemental mercury and oxidized mercury species such as mercuric chloride from flue gases, including those containing acid gases (e.g., SO.sub.2, NO and NO.sub.2, and HCl), over a wide range of temperatures.

Abstract: The present invention relates generally to an environmental control unit for use in air handling systems that provides highly effective filtration of noxious gases (such as ammonia). Such a filtration system utilizes novel metal-doped silica-based gels to trap and remove such undesirable gases from an enclosed environment. Such gels exhibit specific porosity requirements and density measurements. Furthermore, in order for proper metal doping to take effect, such gels must be treated while in a wet state. The combination of these particular properties and metal dopant permits highly effective noxious gas filtration such that uptake and breakthrough results are attained, particularly in comparison with prior silica gel filtration products. Also included is the presence of an oxidizing agent to aid in capturing nitrous oxide and preventing conversion of such a product to NO. Methods of using and specific filter apparatuses are also encompassed within this invention.
