A porous polymer monolith comprises a polymer body having macroporous through-pores that facilitate fluid flow through the body and an array of mesopores adapted to bind from the fluid flow molecules of a predetermined range of sizes, wherein the surface area of the monolith is predominantly provided by the mesopores. Also disclosed is a method of making a porous polymer monolith. The method includes forming a polymer body by phase separation out of a solution containing at least a monomer, a crosslinker and a primary porogen, whereby the body contains multiple macroporous through-pores, wherein the solution further contains a secondary porogen comprising oligomers inert with respect to the monomer and cross-linker but chemically compatible with the monomer so as to form mesostructures within the polymer body during said phase separation, and washing the mesostructures from the body to provide an array of mesopores such that the surface area of the monolith is predominantly provided by the mesopores.

A method for removing impurities from a taurine mother liquor and recovering the taurine mother liquor. The method is used in an ethylene oxide production process for taurine. The last mother liquor of taurine is ion-exchanged through an anion exchange resin; then the anion exchange resin is eluted and regenerated with alkaline solution, and the eluate is collected. The eluate is subjected to ammonia mixing treatment, and the treated mother liquor is generated after the impunity is removed from the eluate by solid-liquid separation. The treated mother liquor can then be returned to the ammonolysis step of taurine production.

A method for treating an aqueous fluid resulting from a fluorine-containing polymer production step, the method comprising: separating the aqueous fluid into a solid component and a filtrate using a filter aid.

An endotoxin adsorbent comprising a crystalline cellulose having a nitrogen atom-containing cationic group can sufficiently remove endotoxin from a material containing endotoxin to be removed and containing a substance having a cationic group and can efficiently remove endotoxin also from a highly viscous material. The nitrogen atom-containing cationic group may be typically a functional group derived from a polyvalent amine and/or a quaternary ammonium salt. The crystalline cellulose having a nitrogen atom-containing cationic group may comprise the nitrogen atom-containing cationic group at a content of 0.05 to 3 meq/dry.Math.g in terms of anion exchange capacity.

Multipart functionalized materials are shown that remove sulfites from beverages and in particular wine. The functionalized materials consist of a solid support material having the ability to link polycarbonyls or polyamines thereto. The polycarbonyls and polyamines remove free and bound sulfites when put in contact with the beverage. The polycarbonyl and polyamine functionalized materials can be used separately or mixed together for accomplishing sulfite removal.
