    Abstract: This invention relates to improved porous solid supports for chromatography and catalysis. The supports are prepared by covalently binding a tether polymer to a solid support, and then blocking the remainder of the support surface with a blocking reagent. The tethered polymer ligands are then covalently bound to the support by graft polymerization reactions.

    Abstract: An adsorptive-filtration media for the capture of waterborne or airborne constituents. The media comprises a granular substrate and an amphoteric compound bonded to the substrate in the presence of a crystal inhibiting agent. The media can also comprise a substrate having a specific gravity of less than 1.0 and an amphoteric compound bonded to the substrate. Another media comprises a substrate with a specific surface area of greater than 0.1 m2/gm and an amphoteric compound bonded to the substrate. Another media includes a granular substrate and a manganese oxide amphoteric compound formed on the substrate. Also disclosed is a pavement material for the capture of waterborne constituents. The pavement material comprises a porous pavement substrate and an amphoteric compound bonded to the substrate. Also disclosed is a method for producing a porous, cementitious material. The method includes the steps of providing and thoroughly mixing cement and aggregate, mixing water with the cement and aggregate into a slurry while maintaining a water to cement ratio of less than one, initiating curing of said slurry under pressure and in the presence of steam, and continuing the curing at ambient temperature and pressure until the cementitious material is substantially dry.

    Abstract: Solid materials have been developed to remove contaminating metals and organic compounds from aqueous media. The contaminants are removed by passing the aqueous phase through the solid materials which can be in molded, granular, or powder form. The solid materials adsorb the metals and the organics leaving a purified aqueous stream. The materials are sol-gel and or sol-gel and granulated activated carbon (GAC) mixtures. The species-specific adsorption occurs through specific chemical modifications of the solids tailored towards the contaminant(s). The contaminated solid materials can then be disposed of or the contaminant can be removed and the solids recycled.
