A relation between heat of adsorption and breakthrough time for low concentrations of organic vapors in air passing a bed of charcoal at room temperature.
The concentration of pollutants in the breathing zone of exposed persons can be determined by adsorption of the pollutants. Condition is that during sampling the pollutants which have to be determined are trapped. A simple model has been developed which predicts with fair accuracy the amount of adsorbent necessary to trap the pollutant molecules which have to be determined.
