Performance of Adsorbents at Various Relative Humidities

Abstract

Test tube-sized samples of an activated coconut charcoal, Whetlerite, and a pyrolized synthetic resin-based adsorbent were challenged with benzene and with methyl ethyl ketone (MEK) vapors in a flowing system at a range of relative humidity from 0 to 95%. The time to initial break, time to equilibrium, and sorptive capacity were observed. In general, although MEK is soluble in water as opposed to benzene being insoluble, adsorbent performance was similar for both vapors. In both cases, adsorbent performance showed marked deterioration above 50% relative humidity. Keywords: Chemicla agents; Adsorption; Desorption; Elution; Filters; Collective protectors; Canisters; Gas masks.
