Abstract
A process for the filtration of biopolymer solutions is described, comprising contacting a biopolymer solution with an adsorbent material having a pH in the range of 8.5 to 10.0, preferably for a period of about 15 minutes. Synthetic calcium silicate and magnesium oxide are the preferred contacting materials.
