    摘要: A system for treatment of a polluted effluent, includes an outer chamber configured to treat the polluted effluent in mixture with a purification slurry including particles of one or more catalysts and/or organoclays, or a mixture thereof. The outer chamber includes (i) a stirring unit consisting of an engine and a stirrer, configured to mix the polluted effluent and the purification slurry to prevent the particles from sinking without causing a turbulence, (ii) a membrane located at the top of the outer chamber through which a treated effluent passes, while preventing the particles of one or more catalysts and/or organoclays from exiting the outer chamber together with the treated effluent, (iii) a membrane cleaning system configured to remove and collect the particles of one or more catalysts and/or organoclays accumulated on the membrane, and re-introducing the particles back to the bottom of the outer chamber.

    摘要: Provided are a humidity conditioning material that adsorbs and desorbs a large amount of moisture, and a production method thereof.
    A humidity conditioning material comprising: a porous silica material having an average pore diameter of 1 nm or more; and a carrier, wherein the humidity conditioning material contains an alkali metal element in an amount of 0.001 wt % or more and less than 1.0 wt %. A method for producing a humidity conditioning material involving the following Step (1), Step (2), and Step (3).
    Step (1): A dispersion medium is mixed with a porous silica material having an average pore diameter of 1 nm or more to obtain a slurry, and an amount of alkali metal element in the slurry is adjusted to be 0.001 wt % to 1 wt % relative to a solid content weight therein.
    Step (2): The slurry obtained in Step (1) is applied to a carrier.
    Step (3): The dispersion medium is removed from the carrier coated with the slurry obtained in Step (2) to yield a humidity conditioning material containing the porous silica material and the carrier.

    摘要: The present invention is directed to affinity chromatography devices that separate a targeted protein or antibody from an aqueous mixture containing the targeted protein or antibody. The chromatography device may contain a stacked membrane assembly or a wound membrane assembly. The membrane assemblies include at least one polymer membrane that contains therein inorganic particles. The polymer membrane and/or the inorganic particles have an affinity ligand bonded thereto. The affinity ligand may be a protein, an antibody, or a polysaccharide that reversibly binds to the targeted protein or antibody. The chromatography device may be repeatedly used and may be cleaned with a caustic solution between uses. The chromatography devices may have a dynamic binding capacity (DBC) of at least 30 mg/ml (or 0.07 micromol/ml) at 10% breakthrough at a residence time of 20 seconds or less.

    摘要: The present invention relates to a method for measuring a polymer modification ratio, and more particularly, to a method for measuring a polymer modification ratio, which includes preparing a first solution by dissolving a polymer mixture containing a modified polymer and an unmodified polymer in a first solvent, injecting the first solution into a column filled with an adsorbent, adsorbing the modified polymer onto the adsorbent, and eluting the first solution in which the unmodified polymer is dissolved, transferring the eluted first solution to a detector, injecting a second solvent into the column to elute the second solution in which the adsorbed modified polymer is dissolved, and transferring the eluted second solution to the detector.
