Influence of Atmosphere Weathering on the Performance of Whetlerite
Abstract
Commercial samples of ASC whetlerite, Lot 2-281, were exposed to specified flows of untreated outdoor air at the Naval Research Laboratory, the Atmospheric Physics facilities of the Argonne National Laboratory, and the Simi Valley Monitoring Station of the Air Pollution Control District of Ventura, California. The exposures were varied from one to 12 months. The air contaminants and moisture parameters were determined. After the exposures, the whetlerite samples were evaluated by CK (cyanogen chloride) tests, by DMMP (dimethyl methyl phosphonate) tests, and for a limited number by AC (Hydrogen cyanide) tests. An analysis of the meteorological and industrial environments on the performance of the whetlerite will be presented. The CK 'life' of whetlerite is essentially destroyed as the result of the exposure to outdoor air during the hot and humid summer months or in warm climates. Whetlerite is relatively stable in outdoor air flows during cool, dry winter months. The results for DMMP life were found to be location dependent. A good correlation was found between the loss of CK activity and the dew point of the air flow.
