摘要： An ion-selective membrane is formed integrally of an ion-selective membrane forming component and a woven-fabric-shaped backing. The ion-selective membrane forming component comprises a cationic polymer component and/or an anionic polymer component and a matrix component. Each of the ionic polymer components is a particulate polymer having an average particle size in a range of from 0.01 to 10 &mgr;m. The woven-fabric-shaped backing has a meshed structure. The ion-selective membrane can be produced by forming it while maintaining a layer of a coating formulation, in which the ionic polymer component is dispersed in a solution or dispersion of the matrix component in an organic solvent, in close contact with the woven-fabric-shaped backing. The ion-selective membrane is useful for the permeation of an electrolyte. An apparatus provided with the ion-selective membrane is also provided.

摘要： A module for extracorporeal purification of a biological fluid includes at least one support or wall defining a compartment which is delimited by an ionic functionalized support or wall, the surface of which is bonded by ionic bonds to a first molecule or macromolecule which exhibits free amine groups to which are covalently bonded a second molecule or macromolecule which exhibits free carboxylic groups which can directly or indirectly form amide, ester or thioester bonds. The invention also includes methods of producing such module.
