The use of activated carbon in CBRN gas masks is very important as it is a key material for filtering and adsorbing hazardous gases and chemicals.
Activated carbon impregnated with copper-silver-molybdenum-triethylenediamine, suitable for use in CBRN gas mask canisters used for personal protection against chemical, biological, nuclear and toxic chemical agents.
When using a filter tank containing activated carbon, the following key points need to be noted:
1. Adsorption capacity of activated carbon
Activated carbon adsorbs toxic gases by physical adsorption and chemical reaction. However, its adsorption capacity is limited. Once activated carbon reaches saturation, it can no longer effectively adsorb harmful substances, so the life of the filter tank is limited. Once the filter tank is used for too long, the activated carbon will lose its protective effect.
2. Exposure time and pollutant concentration
The adsorption effect of activated carbon is closely related to the pollutant concentration and exposure time of the environment. In environments with higher concentrations of pollutants, activated carbon saturates more easily.
