A m-xylene adsorbent contains 94 to 99.9 wt % of a Y molecular sieve and 0.1 to 6 wt % of a matrix. The Y molecular sieve consists of a non-crystal-transformed Y molecular sieve and a Y molecular sieve produced by a crystal transformation. The non-crystal-transformed Y molecular sieve is a mesoporous nano Y molecular sieve, which has a crystalline grain size of 20 to 450 nanometers, contains two types of mesoporous pores, and respectively has most probable pore diameters of 5 to 20 nanometers and 25 to 50 nanometers. The adsorbent is used for adsorptive separation of m-xylene from mixed C8 aromatic hydrocarbons.

A composition for gas storage including a mixture of particles of amorphous macroporous organic polymer (MOP) and particles of a metallic organic framework (MOF).

The invention concerns a device for regenerating activated carbon in the form of porous fibres by electro-Fenton reaction, a method for regenerating activated carbon loaded with organic pollutants using the device of the invention, and the use of a filter consisting of porous fibres of activated carbon, which filter has previously been loaded with organic pollutants by filtration of polluted water or polluted air, as the cathode of an electro-Fenton reaction for regenerating the activated carbon porous fibres loaded with organic pollutants.

A method for making a metal organic framework suspension is described herein. The method includes providing a hybrid material comprising a nano-crystalline metal organic framework comprising micropores and a mesoporous polymeric material comprising mesopores, wherein the nano-crystalline metal organic framework is homogeneously dispersed and substantially present only within the mesopores or void spaces of the mesoporous polymeric material; and wherein the hybrid material has a weight percentage of the metal organic framework in the range of 5-50% relative to the total weight of the hybrid material. The method includes contacting the hybrid material with a solvent in which the mesoporous polymeric material is soluble, thereby forming a polymeric solution in which the nano-crystalline metal organic framework is substantially homogeneously dispersed and suspended.

A carbon monolith and a process of producing same, the process comprising the steps of: (i) mixing a carbonaceous precursor material with an alkali salt to form a first mixture; (ii) extruding the first mixture produced in step (i) into the shape of a monolith; and (iii) carbonizing the monolith produced in step (ii).

The present invention relates to a multilayer absorbent filtering item comprising: a first layer of a porous activated carbon support disposed on a nonwoven polyester-fibre felt; a second layer, where the surface of the first layer is bonded to a film of polymer and low-foam surfactants (mixture A); and a third layer, where the surface of the second layer is bonded to a film comprising an active ingredient and a low-foam surfactant in an acid aqueous medium (mixture B), the top face of said polymer film being bonded to the active ingredient, and the bottom face thereof adhering to the activated carbon, by means of polar and non-polar interactions. Also disclosed are a method for obtaining the multilayer absorbent filtering item and the use of the multilayer absorbent filtering item.

The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group. In some examples, the present disclosure can include a chromatographic system having a chromatographic column having a stationary phase with a chromatographic substrate containing silica, metal oxide, an inorganic-organic hybrid material, a group of block copolymers, or a combination thereof.

Drug disposal devices and systems for reducing the amount of drug contained in a transdermal drug delivery patch are disclosed. The drug disposal devices contain an adsorbing substance, such as activated carbon, and are capable of adsorbing residual drug from the transdermal patch and preventing back-extraction of the drug. Also disclosed are methods of manufacturing the drug disposal devices and methods of using the drug disposal devices for reducing the amount of drug contained within a transdermal drug delivery patch.

Disclosed is a composition for the purification of biofluids, for example, for hemodialysis and peritoneal dialysis, comprising an osmotic agent and a toxin-removal reagent, wherein the toxin-removal reagent can remove a toxin from a biofluid under a condition for osmosis. Provided are a dialysis solution and a kit comprising the aforementioned composition, a method for removing a toxin from a biofluid using the aforementioned composition, and a method for treating a toxin-related disease.
