Sorbent compositions that includes a base sorbent material having a high porosity and surface area and a boron-selective agent are particularly useful for the sequestration of boron from waste materials such as coal combustion residual leachate (CCRs). By using a boron-selective agent in conjunction with a high surface area base sorbent material such as activated carbon or biochar, a sorbent composition with a high capacity for sequestering boron at relatively low cost is provided.

This invention relates to a hybrid ligand, a hybrid biomimetic chromedia and a preparing method and a use thereof, wherein the hybrid biomimetic chromedia takes hydrophilic porous microsphere as a substrate in chromatography, activated with allyl bromide and undergoing bromo-alcoholization with N-bromosuccinimide, then coupled with the hybrid ligands. The sequence of the hybrid ligand is phenylalanine-tyrosine-glutamine-5-aminobenzimidazole. The hybrid biomimetic chromedia has both of the two functional groups of phenylalanine-tyrosine-glutamine tripeptide and aminobenzimidazole, while maintaining the high antibody selectivity of polypeptide ligand, hydrophobic electric charge inductive ligand is introduced to achieve more moderate elution requirement, realizing effective antibody separation.

Provided are beads for blood processing having porous beads and a polymer carried on the surface of the porous beads, wherein: the porous beads are configured from at least one resin selected from the group consisting of acrylic resins, styrene resins, and cellulose resins; and the polymer includes a specific monomer defined in the description as a monomer unit.

The invention concerns methods of removing undesirable molecules from the blood or physiologic fluid; said method comprising contacting said blood or physiologic fluid with a sorbent, said sorbent comprising a plurality of solid forms and comprising a cross-linked polymeric material having a plurality of ligands attached to the surface of said cross-linked polymeric material, comprising (i) zwitterionic moieties, (ii) oligo(ethylene glycol) moieties or (iii) mixtures thereof; said contacting comprising said sorbent sorbing a plurality of said undesirable molecules when said sorbent is administered within a patient's body.

The present invention provides novel chromatographic materials, e.g., for chromatographic separations, processes for its preparation and separations devices containing the chromatographic material; separations devices, chromatographic columns and kits comprising the same; and methods for the preparation thereof. The chromatographic materials of the invention are high purity chromatographic materials comprising a chromatographic surface wherein the chromatographic surface comprises a hydrophobic surface group and one or more ionizable modifier.

This present invention discloses a bifunctional adsorptive material capable of adsorbing both cations and anions in aqueous phase, obtainable by synthesizing aluminum ion doped SBA-15 molecular sieves from P123 triblock copolymers, tetraethoxysilane, and aluminum isopropoxide to obtain multiple cationic active adsorption sites, and by grafting large sterically hindered organic groups onto the surface of Al-SBA-15 to obtain multiple anionic active adsorption sites. This kind of adsorptive material has two types of adsorption sites for ions of opposite charges. The large sterically hindered organic groups prevent spontaneous recombination reaction between the two types of adsorption sites, enabling the adsorptive material to have excellent adsorption capacity for wastewater treatment involving both cations and anions.

Provided are a ligand-bearing substrate which has a surface at least partially coated with a polymer (P3) containing structural units represented by the formulae (1a) and (1b) (in the formulae, R.sup.1, R.sup.2, X, Y, L, Q.sup.1, Q.sup.2, Q.sup.3, m1, m2 and n are as described in the claims and description); a raw material for such a substrate; and a method for producing such substrates.

A dual ligand sol-gel sorbent and method of manufacture is provided herein. The dual ligand sol-gel sorbent provides superior enrichment effects through simultaneous exploitation of superhydrophobicity of one of the ligands and the ability of the other ligand to undergo - interaction with hydrophobic aromatic analytes. Sorbent performance is enhanced both in terms of analyte enrichment and sorbent stability, such as pH stability and solvent stability.
