CELLULOSE HYDRATE MEMBRANE, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF

摘要

There is provided a cellulose hydrate membrane having a porous double structure which consists of micropores having a diameter in the range from >100 nm to 20μm and ultrapores which have a diameter of <100 nm and which are not accessible to Blue Dextran having an average molecular weight Mw of 2 000 000, wherein the fraction of the volume of the ultrapores is more than 15% of the entire pore volume accessible to water. In addition, a method for producing the membrane, its use as an adsorption membrane, and an apparatus for membrane chromatography are specified.
