Abstract

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.

Claims (19)

1. A composition of matter, comprising:

unstabilized nano-Se composite having high mercury capture comprising:

nano-Se particles situated on a support.

2. The composition of matter of claim 1 , wherein the nano-SE is crystalline.

3. The composition of matter of claim 1 , wherein the nano-SE is a plurality of closely-packed and connected nano-SE particles.

4. The composition of matter of claim 1 , wherein the nano-SE is mixed with inert matter.

5. The composition of matter of claim 1 , wherein the nano-SE is mixed with active matter.

6. The composition of matter of claim 1 , wherein the nano-SE is mixed with inert matter and active matter.

7. The composition of matter of claim 1 , wherein the nano-SE is mixed with a material selected from a group consisting of: silica, carbon black, and activated carbon.

8. A composition of matter, comprising:

unstabilized nano-Se composite having high mercury capture comprising:

nano-Se particles and a reducing agent situated on a support.

9. The composition of matter of claim 8 , wherein the reducing agent is ascorbic acid.

10. The composition of matter of claim 8 , herein the nano-SE is amorphous.

11. The composition of matter of claim 8 , wherein the nano-SE is crystalline.

12. A composite having high mercury capture, comprising:

unstabilized nano-Se particles situated on a support.

13. The composite of claim 12 , further comprising:

a reducing agent situated on the support.
