In one aspect, a composite porous composition is disclosed, which comprises a porous structure including a plurality of pores, and a plurality of functional particles distributed within at least some of said pores of the porous structure, wherein the particles comprise porous particles.

The method according to this disclosure is a method for separating an unsaturated hydrocarbon having 2 or 3 carbon atoms and a halogenated unsaturated carbon compound formed by replacing at least one of hydrogen atoms included in the unsaturated hydrocarbon with a fluorine atom, from each other and is a method for selectively adsorbing either the unsaturated hydrocarbon or the halogenated unsaturated carbon compound by a porous coordination polymer that includes a metallic ion having a valence of 2 to 4 and an aromatic anion having 1 to 6 aromatic ring(s).

Methods, compositions, devices and kits having a novel chromatographic material are provided herein for separating and identifying organic molecules and compounds, for example molecules and compounds containing electron rich functional groups such as carbon-carbon double bonds. The methods, compositions, and kits include a metal-thiolate chromatographic medium (MTCM) with a sulfur-containing functional group or a metal-selenolate chromatographic medium (MSCM) comprising a selenium-containing functional group covalently attached to a support medium, such that the sulfur-containing functional group or selenium-containing functional group is bound to at least one metal atom. The MTCM and/or MSCM has affinity and specificity to compounds having one or more carbon-carbon double bonds, and performs a highly efficient and rapid separation of samples yielding non-overlapping peaks of purified materials compared to traditional media.

A method of disinfecting an artificial turf structure includes applying to the artificial turf

A method of chromium removal from wastewater comprising providing a copper augmented biochar and contacting the copper augmented biochar with the wastewater to remove chromium from the wastewater. The copper augmented biochar can remove chromium from wastewater with about 99% efficiency in about 1 hour.

A xenon capture system that reduces the concentration of xenon in a carrier gas is disclosed. An example xenon capture system includes a carrier gas with a first concentration of xenon that flows through an intake into a chamber. Within the chamber is a reaction area that has at least one peripheral sidewall. The reaction area operates at a predetermined temperature, flow rate, and low pressure. Within the reaction area is at least one xenon capture mechanism that is at least partially formed of a transition metal. When the carrier gas is exposed to the xenon capture mechanism, the xenon capture mechanism adsorbs xenon from the carrier gas. The carrier gas, with a second concentration of xenon, exits the chamber through the exhaust outlet.

A modified active carbon material for adsorption of airborne lower aldehydes. The activated carbon is impregnated with triethylenediamine (TEDA) and has a copper deposition. A filter media is formed from a method of preparing triethylenediamine (TEDA) activated carbon with deposited copper for removal of toxic formaldehyde from the environment, such as a process of making surface modified granular activated carbon media that is highly efficient in removing formaldehyde.

A method is described for preparing a sorbent comprising the steps of: (i) mixing together a particulate copper sulphide material and a particulate calcined rehydratable alumina, (ii) shaping the mixture, and (iii) drying the shaped mixture to form a dried sorbent.

A method is described for preparing a sorbent comprising the steps of: (i) forming agglomerates comprising a particulate support material, (ii) coating the agglomerates with a coating mixture powder comprising a particulate copper sulphide and a particulate calcined, rehydratable alumina to form a coated agglomerate, and (iii) drying the coated agglomerate to form a dried sorbent.

A method is described for preparing a sorbent precursor comprising the steps of: (i) forming agglomerates comprising a particulate support material, (ii) coating the agglomerates with a coating mixture powder comprising a particulate sulphidable copper compound and a particulate calcined, rehydratable alumina to form a coated agglomerate, and (iii) drying the coated agglomerate to form a dried sorbent precursor. The sorbent precursor may be sulphided and used to remove heavy metals such as mercury from fluid streams.
