| Abstract |
Expressions developed previously to assess the service-life of respirator cartridges exposed to binary systems were extended to address multicomponent mixtures. The procedure was tested by obtaining experimental breakthrough data for mixtures of compounds with widely varying breakthrough properties. Data showed that as exposure proceeds, a compound that is adsorbed relatively weakly by the carbon bed may be displaced by a more strongly adsorbed component. The approach described accounts for this displacement phenomenon which significantly influences the service-life of respirator cartridges exposed to multicomponent systems. |
