  • Separation Using Semi-Permeable Membranes (AREA)

Abstract

PURPOSE:To obtain a membrane having selective permeability to water and having sufficient durability, a high penetration rate for water and a high separation coefficient, by crosslinking polyacrylic acid or a metal salt thereof with a polyfunctional amine. CONSTITUTION:Polyacrylic acid is mixed with a polyfunctional amine such as sodium 2,5-diaminobenzenesulfonic acid etc. to prepare an aqueous solution. The resulting solution is poured and spread on a polyether sulfone ultrafilter and heated to crosslink the polyacrylc acid. This coating is repeated to obtain a composite membrane. The thus-obtained membrane made of polyacrylic acid crosslinked with the polyfunctional amine can be used not only as a membrane having selective permeability to water to be used in the pervaporation of the vapor-penetration method but also as a reverse-osmotic membrane and a dehumidifying membrane for use in the air.
