Title:
一価陽イオン選択透過性陽イオン交換膜及びその製造方法
Document Type and Number:
Japanese Patent JP4759781
Kind Code:
B2
Abstract:
The present invention provides a cation exchange membrane which has excellent durability, a high limiting current density, a low direct current membrane resistance and excellent selectivity to monovalent cations. In the present invention, a cation exchange membrane excellent in selective permeability to monovalent cations is produced by bringing high molecular cations into contact with a surface of a cation exchange membrane in the presence of anions of an oxyacid or anions of an organic sulfonic acid.
