<p>The present invention relates to a preparation method of polysulfone hollow fiber membrane for removing a virus and, more specifically, to a preparation method of polysulfone hollow fiber membrane for removing a virus, where the hollow fiber membrane is manufactured by spinning an internal coagulating agent and a spinning solution with a polysulfone resin, an organic solvent and a water-soluble polymer through a double tubular nozzle, out to the air, and then by solidifying the same with an external coagulating agent, and setting the internal coagulating solution temperature to be 5-10°C higher than the temperature of the raw spinning solution.</p> |
