ABSTRACT:
The invention relates to a method for separating proteins from liquid media, comprisingproviding a liquid medium containing proteins,providing a clay material which has:a specific surface greater than 150 m2/g,a pore volume greater than 0.35 ml/g,an ion exchange capacity greater than 40 meq/100 g, anda sediment volume in water of less than 15 ml/2 g,equilibrating said clay material to a pH of from 3.5 to 9.0,treating said liquid medium with the equilibrated clay material, andseparating the purified, protein-depleted liquid medium from the clay material.
