Treatment of cellulosic ion exchange composites in hot aqueous medium to increase adsorption of macromolecules |
| abstract |
A composite containing DEAE-cellulose agglomerated with a hydrophobic polymer is treated with tap water, deionized water or a dilute salt solution at a temperature of at least 60 DEG C. for a time sufficient to increase adsorption capacity for charged macromolecules by at least about 30%. Treatment is preferably at a temperature of about 80 DEG to about 100 DEG C. for a time period of about one-half hour to about 5 hours. The macromolecule is preferably a protein such as the enzyme, glucose isomerase. |
