Improvement of the efficiency of ion-exchange cellulose columns and their application.

Packing procedures and operating conditions for microparticulate ion-exchange cellulose columns were investigated. The efficiencies of ion-exchange cellulose and mixed-bed ion-exchange cellulose columns were compared. The mixed-bed columns contained ion-exchange cellulose and diatomite, and those with a 5:1 volume ratio of ion-exchange cellulose (average particle size 7 micronm) and diatomite were found to be superior in almost every respect. Medical, pharmaceutical, biochemical and environmental applications of this type of column are shown.
