Abstract
A reactive-adsorptive protective material having an activated carbon adsorbent, including those manufactured from a gel-type ion exchange resin. The activated carbon adsorbent has adsorptive properties for adsorbing chemical impurities. The activated carbon is wettlerized to further impart reactive properties onto the activated carbon for providing protection against blood agents in the atmosphere. Advantageously, a superior reactive-adsorptive material is provided having the ability to neutralize chemical substances, in particular, blood agents, while at the same time not diminishing the effectiveness of the carbon's adsorption capabilities.
Claims22
A method of providing a reactive-adsorptive protective material comprising the steps of:
- producing activated carbon having a BET surface area on the order of 1500 m2/g for providing adsorptive properties and a pore size distribution having about 80% of the pores below 40 Å;
- and
- loading metal ions onto the activated carbon to further impart reactive properties onto the activated carbon for providing protection against blood agents which are in contact therewith, wherein the pore size distribution results in metallic ion take up without measurably diminishing the surface area;
- impacting finely-divided inorganic metal oxide nanocrystals onto said activated carbon to topographically imbed the nanocrystals to provide chemical or biocidal protection.
