Filed:

Oct 8, 2004
Appl. No.:

10/961932
Inventors:

Lena Q. Ma - Gainesville FL, US
Thomas Luongo - High Springs FL, US

Nandita Singh - Kaiserbagh, IN
Assignee:

University of Florida Research Foundation, Inc. - Gainesville FL
International Classification:

C22B 3/18
C22B 3/24
US Classification:

47 581, 800298, 210602, 210682, 75710, 75711, 75712
Abstract:

Processes, methods, materials and compositions for phytoremediating contaminated waters, which have been contaminated with pollutants such as arsenic. Fern plants that include and non-fern plants can be used to accumulate pollutants from contaminated water, including aqueous solution, waste water, ground water, surface water, combinations thereof. Pollutants and contaminants can be removed from the water, soil and wetland type environment via phytoremediation through roots and fronds as well as by applying excised portions of plants such as leaflets (cut-off fronds). The biomass can be harvested and readily disposed of, or can be treated to recover the pollutants and contaminants.

75711, 75710, 75712, 210602, 210681, 47 581, 800298, 800295
Abstract:

Processes, methods, materials and compositions for phytoremediating contaminated waters, which have been contaminated with pollutants such as arsenic, phosphorous, or other metals. Fern plants can be used to accumulate pollutants from contaminated water, including aqueous solution, waste water, ground water, surface water, combinations thereof. Pollutants and contaminants can be removed from the water, soil and wetland type environment via foliar application, excised leaflets, and/or through compositions of ground leaflets. The biomass can be harvested and readily disposed of, or can be treated to recover the pollutants and contaminants.

Assignee:

University of Florida Research Foundation, Incorporated - Gainesville FL
International Classification:

C22B 3/18

US Classification:

47 581, 800298, 210602, 210682, 75710, 75711, 75712
Abstract:

Processes and materials for phytoremediating water-containing sites which have been contaminated with pollutants such as arsenic, phosphorous, or other metals. Fern plants can be used to accumulate pollutants from contaminated water-containing sites having an aqueous solution, waste water, ground water, surface water, combinations thereof, and combinations of water-containing sites with soils and/or sediments. The fern plants remove pollutants from the water-containing sites, and can be harvested and readily disposed of, or can be treated to recover the pollutant.
