Abstract
A method for purifying breathing air using a carbon-based monolith structure impregnated with copper, silver, zinc, and molybdenum species and triethylenediamine, wherein the monolith structure is impregnated by a multiple step process. The method of impregnation results in a carbon-based monolith structure that purifies nuclear, biological, or chemical contaminants under conditions of high flow rate and low pressure drop.
