Abstract
Porous cellulose beads are prepared by distributing droplets of a solvent mixture containing a cellulose derivative into a precipitating solution to form porous beads which are then washed and hydrolyzed to form porous cellulose beads. The porous cellulose beads, which may be cross-linked, if desired, by suitable treatment, are useful carriers to which enzymes can be immobilized. The beads may also be used for the separation of enzymes, proteins, nucleic acids and the like, or to remove metal ions from dilute mining solutions.
