A first process and sorbent for removing ammonia from a gaseous environment, the sorbent comprised of graphene oxide having supported thereon at least one compound selected from metal salts, metal oxides and acids, each of which is capable of adsorbing ammonia. A second process and sorbent system for removing ammonia and a volatile organic compound from a gaseous environment; the sorbent system comprised of two graphene-based materials: (a) the aforementioned graphene oxide, and (b) a nitrogen and oxygen-functionalized graphene. The sorbents are regenerable under a pressure gradient with little or no application of heat. The processes are operable through multiple adsorption-desorption cycles and are applicable to purifying and revitalizing air contaminated with ammonia and organic compounds as may be found in spacesuits, aerospace cabins, underwater vehicles, and other confined-entry environments.

The purpose of the present invention is to provide a granulation adsorbent having high strength and in particular stability in water that ensures certain throughputs at low costs. The granulated adsorbent of the invention comprises a metal-cyano complex as an effective component, a flocculation precipitant for flocculation precipitation of the metal-cyano complex from slurry containing the metal-cyano complex, a binder, and a crosslinking agent. The granulated adsorbent is produced by a step of adding the flocculation precipitant to the metal-cyano complex slurry and then dehydrating the metal-cyano complex slurry to prepare a metal-cyano complex dehydrated cake, a step of heat drying the metal-cyano complex dehydrated cake to prepare a metal-cyano complex dried block, a step of pulverizing the metal-cyano complex dried block into metal-cyano complex powder, and a step of preparing a mixture containing the metal-cyano complex powder, binder and crosslinking agent, and then granulating using the mixture.

The present invention relates to a radionuclide adsorbent, which includes a hollow space (specifically, an area which is entirely empty or in which transition metal oxide particles are present); and a transition metal-ferrocyanide shell (specifically, a transition metal-ferrocyanide shell having a structure in which a plurality of two-dimensional nano flakes overlap or a transition metal-ferrocyanide shell having a structure in which a plurality of three-dimensional nano polyhedrons agglomerate) formed on the space surface, a preparation method thereof, and a method of removing a radionuclide using the same.

A method of water treatment includes flowing water that includes nitrogen and phosphorus compounds through a sorption media composition within at least one chamber of a water treatment system. The composition comprises iron filings comprising at least 5 volume (vol) % of the composition, sand particles comprising at leak 10 vol % of the composition, and clay particles comprising at least 2 vol % of the composition. The iron filings, sand particles, and clay particles are mixed together. During the flowing, the clay particles attract the nitrogen and phosphorus compounds, which become absorbed onto a surface of the iron filings and the clay, resulting in a removal of the nitrogen and phosphorus compounds and the generation of reaction products. Nitrogen and phosphorus are then recovered from the reaction products.
