  • Method for removal of explosives from aqueous solution using suspended plant cells
    Patent number: 5296146
    Abstract: The use of plant suspension cultures to remove ionic metallic species and TNT-based explosives and their oxidation products from aqueous solution is described. Several plant strains were investigated including D. innoxia, Citrus citrus, and Black Mexican Sweet Corn. All showed significant ability to remove metal ions. Ions removed to sub-ppm levels include barium, iron, and plutonium. D. innoxia cells growing in media containing weapons effluent contaminated with Ba.sup.2+ also remove TNT, other explosives and oxidation products thereof from solution. The use of dead, dehydrated cells was also found to be of use in treating waste directly.
    Type: Grant
    Filed: June 8, 1992
    Date of Patent: March 22, 1994
    Assignees: The Regents of the University of CA, Los Alamos National Laboratory
