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.
