OIL-ABSORPTIVE POROUS HOLLOW FIBER MEMBRANE AND REMOVING METHOD FOR ORGANIC SOLVENT IN WATER WITH THE MEMBRANE

摘要

PURPOSE: To remove an organic solvent and dust in water by using a porous hollow fiber membrane made by allowing an oil-absorptive crosslinked polymer composed of a non-cross-linkable monomer containing (metha)acrylate of a specific univalent aliphatic alcohol and a cross-linkable monomer to be carried onto the narrow pore surface of a part of the porous hollow fiber membrane. ;CONSTITUTION: The oil-absorptive porous hollow fiber membrane is constituted by allowing the oil-absorptive cross-linked polymer composed of 100 pts.wt. non-cross-linkable monomer containing (metha)acrylate of 10-16C univalent aliphatic alcohol and 0.001-5 pts.wt. cross-linkable monomer to be carried onto the narrow pore surface of at least one part of the porous hollow yarn membrane. Scale, dust and the organic solvent such as trihalomethane, oil are removed by using the membrane.;COPYRIGHT: (C)1994,JPO&Japio
