Abstract: Shaped lyocell cellulose articles are provided for binding heavy metal ions and radioactive isotopes thereof. The shaped articles include one or more hexacyanoferrates that are incorporated in a cellulosic matrix and uniformly distributed therein. The shaped articles can be fibers, fibrids, fibrous nonwoven webs, granules, beads, self-supporting films, tubular films, filaments, sponges, foams or bristles. They are useful for water treatment and water decontamination, for metal beneficiation, for treatment of wound with wound dressings, for air and gas filtration and in protective apparel.
