Abstract

Biomasses of mycelia of microorganisms, particularly of fibrous fungi used for retention of metal ions from solutions, particularly of uranium, radium, lead and similar are stiffened by adding polymerizable components to them by polymerization, and the product is subsequently mechanically granulated. The granulated product is then employed in cyclically repeated sorption processing of heavy metal ions by contacting it with solutions of such metals.
