    摘要: A fluorine resin polymer separation membrane and a manufacturing method of the same, which are excellent in a virus-eliminating property, further excellent in water permeability, chemical strength (chemical resistance), physical strength, and an antifouling property, and particularly suitable for practicable use as a filtration membrane for the elimination of viruses, are provided. A fluorine resin polymer separation membrane includes a layer having a three-dimensional network structure and a layer having a spherical structure, in which the layer having a three-dimensional network structure does not substantially contain micro-voids having a void diameter of 5 μm or more, and the fluorine resin polymer separation membrane has filtration performance represented by the elimination rate of 80% or more of dextran having molecular weight of 75,000. The layer having a three-dimensional network structure is formed by the solidification with a polymer solution containing a fluorine resin polymer and cellulose ester.

    摘要: The invention provides a polymer separation membrane that is excellent in separating characteristics, a permeating ability, a chemical strength (particularly chemical resistance) and a physical strength, and also excellent in a stain resistance, and a producing method therefor. The fluorinated resin-type polymer separation membrane includes a layer having a three-dimensional network structure, and a layer having a spherical structure, wherein the layer of three-dimensional network structure is formed by a fluorinated resin-type polymer composition containing a hydrophilic polymer, and the hydrophilic polymer is a substantially water-insoluble hydrophilic polymer containing at least one of a cellulose ester, an aliphatic vinyl ester, vinylpyrrolidone, ethylene oxide and propylene oxide as a polymerization component. The polymer separation membrane is applicable as a filtration membrane for water treatment, a battery separator, a charged membrane, a fuel cell membrane or a blood cleaning filtration membrane.

    摘要: Disclosed is a method for producing an aqueous refined sugar solution, in which a biomass residues that are formed during a step of producing a sugar from a cellulose-containing biomass is removed in a step of producing an aqueous sugar solution, thereby preventing the clogging of a microfiltration membrane and/or an ultrafiltration membrane and ensuring long-term, stable production of an aqueous refined sugar solution. Specifically disclosed is a process for producing an aqueous refined sugar solution using a cellulose-containing biomass as a raw material, which comprises the steps of: (1) decomposing cellulose-containing biomass to produce an aqueous sugar solution; (2) subjecting the aqueous sugar solution resulting from step (1) to aggregation treatment with an aggregation agent to produce an aqueous sugar solution having an average particle diameter of 2 μm or more as determined by particle size distribution measurement; and (3) filtering the aqueous sugar solution resulting from step (2) through a microfiltration membrane and/or an ultrafiltration membrane and subsequently recovering an aqueous sugar solution from the downstream side.
