摘要:
A sorbent in the form of a layered, non-porous perovskite is provided, wherein the sorbent can include parallel, alternating layers of an organic layer, including an ordered array of organic moieties capable of reacting with a gaseous halogen, and an inorganic layer, including a metal-halide sheet. Furthermore, each organic layer can be sandwiched between inorganic layers. Methods for capturing one or more halogens from a gas stream are also provided, wherein the methods can include contacting a gas stream with a sorbent in the form of a layered, non-porous perovskite, wherein the sorbent can include parallel, alternating layers of an organic layer, including an ordered array of organic moieties capable of reacting with a gaseous halogen, and an inorganic layer, including a metal-halide sheet.

Provided is an organic ligand-bound metal surface that selects one gaseous species over another. The species can be closely sized molecular species having less than 1 Angstrom difference in kinetic diameter. In one embodiment, the species comprise carbon monoxide and ethylene. Such organic ligand-bound metal surfaces can be successfully used in gas phase separations or purifications, sensing, and in catalysis.

Claims 1 -5 relate to methods for treatment of the human or animal body by therapy, since the claims describe changing the compositions of the circulation dialysis fluid, which will affect the ion concentration in the patient's blood. See PCT rule 43bis.1 (b) and PCT rule 67.1.(iv). Nevertheless, an examination has been conducted for these claims. The examination has been made in respect of the technical content of the claims.
摘要:
A solid support or resin for argentation chromatography is provided, comprising a chitosan polymer which has been sulfonated and loaded with silver. The solid support can be used for chromatographically separating saturated fatty acids from unsaturated fatty acids in a mixture, and optionally also for separating trans and cis unsaturated fatty acids. The chitosan polymer has sulfonate groups complexed to silver ions. Suitable sulfonate groups include RSO 3 -, where R can be an alkyl group, an aryl group or a benzoyl group. More particularly, the sulfonate groups are -(CH 2 ) n SO 3 -, where n = 0, 1, 2 or 3; or (C=O)RSO 3 -, where R is an aryl group. The fatty acids can be fatty acid methyl esters (FAMEs). The chitosan polymer can be formed from naturally occurring chitosan or from a chitosan derivative, such as any one of sulfonamide chitosan, 2- N -sulfopropyl chitosan, 2-N- sulfobenzamido chitosan, 6-deoxy-amino chitosan, sulfonamide-6-deoxy 6- amino chitosan, 6-deoxy-2,6- bis -[sulfopropyl] chitosan, and 6-deoxy-2,6-bis- [sulfobenzamido] chitosan.
