Abstract

The present invention involves the use of nanoporous carbons derived from partially or fully demetalized metal carbides in personal protection equipment for the irreversible absorption/adsorption of both broad and specific targeted gases. These materials have been specifically processed to provide enhanced effective loadings against specific harmful volatile organic compounds.

Claims (9)

1. A method of making a chemical filtration media comprising the step of:

adding an amount of 5 M nitric acid to an amount of Mo 2 C in a container to form a carbide derived carbon;

equipping the container with a condenser;

heating the container;

filtering said carbide derived carbon; and

drying said carbide derived carbon under vacuum.

2. The method of making a chemical filtration media of claim 1 , wherein the step of heating the container further comprises placing the container on a pre-heated heating block.

3. The method of making a chemical filtration media of claim 1 , wherein the step of filtering said carbide derived carbon further comprises filtering said carbide derived carbon through a sintered glass flannel.

4. The method of making a chemical filtration media of claim 1 , further comprising the step of: rinsing with an amount of distilled water until said amount of distilled water becomes neutral.
