  • Method of producing an activated cation-retaining sorbent through formation of a microcrystalline precipitate which adheres in the pores and on the surface of the sorbent
    Patent number: 4124544
    Abstract: Waste waters, particularly waste waters with radioactive contamination, are cleaned by a sorption-precipitating process, where the sorbent retaining cations are regenerated that is, activated, by a solution, the cationic component of which forms with anionic contaminations a precipitate, taking along cationic contaminations, and simultaneously sticking on the surface and within pores of the sorbent.

  • Process of treating mycelia of fungi for retention of metals
    Patent number: 4021368
    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.
