ABSTRACT:
Porous material particularly suitable for selective sorption and retention of macromolecules are manufactured by mixing a finely divided inorganic material with a fugitive additive, forming into discrete particles and heat treating to remove fugitive additive. The fugitive additive is a solid which is preferably mixed with the inorganic material after dissolving the additive in a solvent which is not a solvent for the inorganic material.
