Nanostructured sorbent materials for capturing environmental mercury vapor
The present invention is a method and material for using a sorbent material to capture and stabilize mercury. The method for using sorbent material to capture and stabilize mercury contains the following steps. First, the sorbent material is provided. The sorbent material, in one embodiment, is nano-particles. In a preferred embodiment, the nano-particles are unstabilized nano-Se. Next, the sorbent material is exposed to mercury in an environment. As a result, the sorbent material captures and stabilizes mercury from the environment. In the preferred embodiment, the environment is an indoor space in which a fluorescent has broken.
1. A method for using a packaging material to capture and stabilize mercury, comprising:
providing a packaging material containing a sorbent material for capturing mercury, the sorbent material comprising unstabilized, nano-Se particles;
positioning packaging material over mercury spillage site to capture and stabilize mercury;
whereby the sorbent material of the packaging absorbs the mercury.
2. A method for using sorbent material to capture and stabilize mercury in a container, comprising:
providing a sorbent material, the sorbent material comprising unstabilized, nano-Se particles; and
exposing the sorbent material to mercury in a container,
whereby the sorbent materials captures and stabilizes mercury from the container.
3. The method of claim 2 , further comprising:
providing a carrier material, the sorbent material being carried on the carrier material.
4. The method of claim 3 , where the carrier material is selected from a group consisting of: cardboard, Styrofoam, textiles, paper, and plastics.
5. The method of claim 3 , further comprising:
impregnating the nano-particles into the carrier material.
6. The method of claim 3 , further comprising:
spraying the carrier material with sorbent material.
7. The method of claim 3 , further comprising:
dipping the carrier material into sorbent material.
8. The method of claim 2 , wherein the container is selected from a group consisting of: shipping container, packaging, refuse containers, trash bags, storage bags, boxes, cardboard containers, and recycling containers.
9. A method for using sorbent material to capture and stabilize mercury, comprising:
providing a sorbent material, the sorbent material comprising unstabilized, nano-Se particles; and
exposing the sorbent material to mercury in an environment,
whereby the sorbent material captures and stabilizes mercury in the environment.
10. The method of claim 9 , wherein the environment is selected from a group consisting of: building, office, dentist's office, laboratory, recycling center, store, warehouse, shipping vessel, shipping container, recycling center, container, packaging, storage space, vehicle, landfill, stadium, office park, or any other environment where mercury is found.
11. The method of 9 , wherein the environment is an indoor space in which a fluorescent lamp has been broken.
12. The method of claim 9 , wherein the sorbent material are selected form a group consisting of: micro-scale powder, solutions, soluble compounds, activated carbon, S-impregnated activated carbon, or other chemically modified activated carbons.
13. The method of claim 9 , wherein the sorbent material is supplied on a carrier material to cover the spill site.
14. The method of claim 9 , wherein the sorbent material is supplied on a carrier material in a filter.
15. A method for capturing and stabilizing mercury in the environment, comprising:
providing a nano-Se composite having high mercury capture comprising,
unstabilized nano-Se particles situated on a support; and
exposing the nano-Se composite to mercury in an environment,
whereby the nano-Se composite captures and stabilizes mercury in the environment.
