Abstract

The adsorption characteristics of a respirator cartridge is affected by the kind of adsorbent, concentration of organic vapor, humidity and packing density of cartridge. In this study, activated carbon fiber(ACF) instead of activated carbon is used as a adsorbent of cartridges for the removement of organic vapor and the adsorption characteristics were examined. ACF made of cellulose showes high efficiency for the removal of carbon tetrachloride and the adsorption capacity was 0.569g/g ACF at 450 ppm. The relative humidity dose not affected to the adsorbed amount and Langmuir Isotherm was more adequate than Freundlich Isotherm for this adsorption phenomena.
