Claims10
A membrane for removing substances absorbed thereon comprising a porous substrate having a plurality of pores wherein
- said pores have a polysulfuric compound loaded on their pore surface by an intervening hydrophilic graft chain having a reactive functional group which immobilizes the polysulfuric compound to the reactive functional group;
- wherein said sulfuric group of the sulfuric compound is substantially in the form of a salt;
- and further wherein said hydrophilic graft chain comprises at least one member selected from the group consisting of an acrylamide polymer, a polyether polymer, and a polyalkoxyalkylacrylate polymer.
