    摘要： A pore diffusion type flat membrane separation apparatus X including a plurality of flat membranes 7 and a plurality of flat plate-like supports 1 arranged alternately with each other, each flat membrane 7 defining a plurality of pores and configured to separate a predetermined dispersed substance contained in a solution by a pore diffusion technique, each flat plate-like support 1 having a flow conduit 2 on one or both faces thereof. A ratio between a spatial volume of the flow conduit 2 and a membrane area of the flat membrane 7 is set from 0.04 to 0.4 cm. The flat plate-like support 1 includes, in at least two positions in a lateral face thereof, water conduits 3 in communication with the flow conduit 2, so that flow directions of the solution in the flow conduits 2 of upper and lower flat plate-like supports 1 across the flat membrane 7 may be substantially same directions. The flat plate-like support 1 and the flat membrane 7 can be assembled with and disassembled from each other.

    摘要： A hollow fiber membrane made of a cellulose ester having a membrane thickness of not more than 75 .mu.m, and having void volume (x, % by volume) of the membrane and a rate of ultrafiltration (y, ml/m.sup.2.hr.mmHg) satisfying the following formula:55x-2500.ltoreq.y.ltoreq.48x+600wherein x.gtoreq.60,and further has a .beta.-lipoprotein sieving coefficient (sc) of not less than 0.95, and preferably having further not more than 2% of change ratio in the axial direction and in the radial direction when dipped freely in water at 121.degree. C. for 20 minutes. Said hollow fiber membrane is useful for the medical use, such as the exchange of plasma in patients, collection of plasma from healthy donors, the pre-treatment of plasma for the collection and purification of valuable materials contained in plasma.

    摘要： Process for production of a hollow fiber semipermeable membrane which can selectively separate the components of solution or gas mixtures, which consists essentiallly of dissolving cellulose triacetate and an organic acid and optionally a polyether in N-methyl-2-pyrrolidone to give a spinning solution having fixed contents of cellulose triacetate and organic acid and polyether (if any), and extruding the spinning solution through a spinneret into a gaseous atmosphere and immersing the spun fibers in an aqueous coagulation bath. The hollow fiber semipermeable membrane has excellent permeability and excellent separation characteristics with good life and hence is useful for various techniques such as dialysis, ultrafiltration, reverse osmosis, and separation of gases.

    摘要： A METHOD OF PREPARING A SEMIPERMEABLE MEMBRANE ADAPTED TO PERMIT SUBSTANTIALLY SELECTIVE DIFUSION THERETHROUGH OF A COMPONENT O A SOLUTION. THE MEMBRANE IS PRPARED FROM A SOLUTION CONTAINING A CELLULOSIC ESTER OR ETHER DERIVATIVE AND A WATER-SOLUBLE LIQUID AMIDE HAVING THE FORMULA R6CONR7R8 WHEREIN R6 IS FROM THE CLASS CONSISTING OF HYDROGEN, LMETHYL AND ETHYL GROUPS AND R7 AND R8 ARE FROM THE CLASS CONSISTING OF HYDROGEN, ETHYL AND PROPYL GROUPS WITHOUT BOTH R7 AND R8 BEING HYDROGEN. THE SOLUTION IS CAST ON A SUPPORT. A PORTION OF THE LIQUID ANIDE IS EVAPORATD TO TRANSFORM THE CAST SOLUTION INTO A MEMBRANE. THE CAST MEMBRANE IS THEN IMMERSED IN WATER AND HEATED TO REDUCE ITS POROSITY.
