The invention concerns biocompatible polymer systems comprising at least one polymer with a plurality of pores, said polymer comprising a sulfonic acid salt functionality designed to adsorb a broad range of protein based toxins from less than 0.5 kDa to 1,000 kDa and positively charged ions including but not limited to potassium.

A device for collecting contaminants from water samples is provided. The device includes a solid sorbent that collects and stores the contaminants from water samples. The solid sorbent is configured to allow for the preservation of the stored contaminants. The concentrations of the contaminants in the water samples are determined via analysis of the solid sorbent or via elution of the stored contaminants from the sorbent and analysis of the eluate solution.

The present invention describes a method of capturing a fluorinated carbon compound located within a liquid, the method comprising contacting the fluorinated carbon compound with a block copolymer having a backbone comprising a hydrophilic block and a fluoropolyether block, wherein the fluorinated carbon compound binds to and is captured by the block copolymer.

Crosslinked polymers made up of polymerized units of cyclic diaminoalkane, aldehyde and bisphenol-S or melamine. A method for removing heavy metals, such as Pb(II) from an aqueous solution or an industrial wastewater sample with these crosslinked polymers is introduced. A process of synthesizing the crosslinked polymers is also described.

Polymeric sorbents for carbon dioxide are provided. More particularly, the polymeric sorbents are a reaction product of a divinylbenzene/maleic anhydride precursor polymeric material with a nitrogen-containing compound. The nitrogen-containing compound is covalently attached to the polymeric sorbents. Additionally, methods of sorbing carbon dioxide on the polymeric sorbents and compositions resulting from sorbing carbon dioxide on the polymeric sorbents are provided. The polymeric sorbents typically are porous and can selectively remove carbon dioxide from other gases such as methane or hydrogen.

The invention relates to inorganic particles which are covalently bonded to first polymer chains made up of at least one polymer carrying proton exchange groups, optionally in the form of salts, and bonded to second polymer chains made up of at least one fluorinated polymer that does not carry any proton exchange groups, the second chains being bonded to the particles via organic spacer groups, or the second chains being bonded to first chains via organic spacer groups, or some of the second chains being bonded to the particles via organic spacer groups while the remaining second chains are bonded to first chains via organic spacer groups.

A porous formed article includes an organic polymer resin and an inorganic ion adsorbent and having the most frequent pore size of 0.08 to 0.70 μm measured with a mercury porosimeter. Such a porous formed article can be prepared by crushing and mixing a good solvent for the organic polymer resin and the inorganic ion adsorbent to obtain slurry; dissolving the organic polymer resin and a water-soluble polymer in the slurry; shape-forming the slurry; promoting coagulation of the shape-formed product by controlling the temperature and humidity of a spatial portion coming into contact with the shape-formed product, until the shape-formed product is coagulated in a poor solvent; and coagulating the coagulation-promoted shape-formed product in a poor solvent. A production apparatus can be used to prepare such a porous formed article.

A water-absorbent resin (21) has a shape in which a plurality of particles (40) having a substantially spherical shape is connected in a chain shape.

An air filter including a filter support that supports porous, polymeric sorbent particles that comprise a divalent metal impregnated therein.
