  • Separation Using Semi-Permeable Membranes (AREA)

Abstract

PURPOSE: To produce easily semipermeable membrane material, which is used for dialysis, ultrafiltration, and back osmosis, by the swelling of hollow cellose acete filament with acetic acid or formamide and by making the crossection of the filament circular.
