摘要
A microporous membrane is prepared by treating the cation exchange membrane (Fe+++ form) with an H2O2 aqueous solution. The cation exchange membrane is prepared by the paste method: the base membrane is prepared beforehand and then sulfonated. The preparative conditions of the base membrane were studied in connection with the characteristics of the resultant microporous membrane. Furthermore, the availability of the microporous membrane for ultrafiltration was studied by using an aqueous solution of a bovine hemoglobin. Copyright © 1990 John Wiley & Sons, Inc.
