摘要： The present invention provides a method of making an adsorbent material for protection and sensing applications from gas and liquid phase media by grafting sorbent moieties onto a rigid scaffold. The grafting can be to an organic linker of a metal organic framework by post synthetic modification, to the metal nodes of the metal organic framework via ligand displacement, or by intercalating the sorbent moiety into the pores of the metal organic framework either during formation of the scaffold or by diffusion into the pores after the scaffold is formed.

摘要： An antibiological sorbent can include sorbent material (e.g., porous carbon, activated carbon, inorganic carbon, organic carbon, etc.), antibiological material, optionally a functionalizing material, and/or any other suitable material. The antibiological material (and/or the functionalizing material) can coat, intercalate within (e.g., within a porous network of), form structures on, be disposed on, bind to, and/or otherwise be interfaced to the sorbent material. A method for manufacturing the antibiological sorbent can include: mixing sorbent material with a precursor; optionally, functionalizing (e.g., activating) the sorbent material; forming antibiological material from the precursor; optionally, post-processing (e.g., washing) the resulting material; and/or any suitable steps.

摘要： A method of making granular extrudate by extruding a starch-containing admixture from an extruder into an extrudate discharge chamber in gas flow communication with a discharge conduit that transports the granular extrudate away therefrom in gas turbulently flowing therethrough. During transport of the granular extrudate from the discharge chamber and through the conduit in the flowing gas, the gas quenches the granular extrudate cooling and drying the granular extrudate without heating it. Quenching reduces the granular extrudate temperature by at least 15° Celsius and moisture content to no greater than 13%. Quenching prevents shrinkage and densification of the extrudate including when cut into pellets. Quenching also prevents retrogradation, crystallization/recrystallization and solubilization of cold-water soluble binder formed in each pellet during extrusion. This produces extruded sorbent pellets which are water and oil sorbent, which clump when wetted, and which are well suited for use as cat or animal litter.

摘要： Supported amine polymer adsorbents based on polymers containing only or primarily primary amines sites are to be used as regenerable adsorbents for CO2 capture from ultra-dilute gas streams, such as ambient air, or from mixtures of gases containing preferably at least I 0% oxygen. and can also be useful for use at the moderate gas pressures found in typical post-combustion capture processes, such as flue gas from large point sources such as coal-fired power plants. Preferred supported solid amine adsorbents of this invention are based on poly(allylamine) (“PAA”) and poly(vinyl amine) (“PVAm”), both of which are linear polymers, and their derivatives, containing substantially all primary amine groups, supported on substrates. Preferred such substrates include silica mesocellular foam (MCF) and mesoporous-.gamma.-alumina, as well on mesoporous-.gamma.-alumina coated throughout the pores of MCF, most preferably of monolithic structure. Preferred derivatives include the guanidinylated and cross-linked poly(allylamine) materials.

摘要： A product for adsorbing one or more PFAS from a liquid is disclosed. The product may comprise attapulgite that has been surface functionalized with (a) a quaternary amine surface coating solution that comprises a mono-quaternary amine compound or a di-quaternary amine compound and (b) a mercapto surface coating solution that comprises a surface coating agent that includes one or more mercapto groups that chemically bond to the attapulgite surface. When the quaternary amine surface coating solution includes the mono-quaternary amine compound, the product is free of di-quaternary amines. When the quaternary amine surface coating solution includes the di-quaternary amine compound, the product is free of mono-quaternary amines. Also disclosed is a method of producing the product and a method of adsorbing a PFAS in a liquid using the product.

摘要： There is disclosed, a desalination apparatus making use of a particles including covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent. For example, the complexing agent may include a crown ether. The particles are optionally used for removing salt from water, for example sea water. The apparatus optionally includes a magnet for magnetic filtering, concentrating and/or removing the particles and/or contaminant (e.g., salt). In some embodiments, the salt is then separated back from the particles using UV light. The remaining unclarified water may be washed out with the contaminant and/or used for salt production and/or disposed of (e.g., dumped back to the sea). Optionally, the particles are regenerated. For example, the regenerated particulars may be reused for further desalination steps (e.g., further salt removal from the clarified water) to clarify new input water. Covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent are also disclosed.
