摘要: Supported amine polymer adsorbents based on polymers containing only or primarily primary amines sites are to be used as regenerable adsorbents for CO.sub.2 capture from ultra-dilute gas streams, such as ambient air, or from mixtures of gases containing preferably at least 10% 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: The present invention relates to a super-absorbent polymer having excellent properties, both centrifugal retention capacity (CRC) and absorption under pressure (AUP) having been improved by introducing a surface crosslinked layer crosslinked by surface-modified inorganic particles, and to a method for preparing the same. The super-absorbent polymer comprises: a base resin powder containing a crosslinked polymer of water-soluble ethylene-based unsaturated monomers having an at least partially neutralized acidic group; and a surface crosslinked layer formed on the base resin powder, wherein inorganic particles may be chemically bound to the crosslinked polymer contained in the surface crosslinked layer, via an oxygen-containing bond or a nitrogen-containing bond.

摘要: A method of removing and detecting the presence of substances from at least one of a body of water and the air. The method includes placing into the body of water or into the air an open-cell foam material, removing separate portions of the open-cell foam material from the water or air at different exposure times after the open-cell foam material was placed into the water or air, and determining the presence in the removed separate portions of one or more substances that were removed from the water or air by the open-cell foam material.

摘要: A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.
