Abstract
This invention relates to ion-exchanged fine cellulose particles, porous fine cellulose particles which can be advantageously used as an affinity carrier, and methods of production thereof. These fine particles of the invention have the advantage that they possess excellent pressure-resistant strength and can treat treatment liquors under pressure at a high flowing velocity. Thus, they can be advantageously used industrially in various separation and purification processes.
