Effect of Chemical Purity on Measurement of Agent Resistance and Decontamination Performance for Materials
Abstract
There is a need to understand and predict how decontamination technologies will work on real assets in the field upon contamination with actual chemical weapons (i.e., not refined laboratory-grade agents). Current methodologies primarily focus on the testing of clean, ideal materials, such as flat, horizontal surfaces in a laboratory environment, using highly purified agents. The magnitude of the effects of the dominant mechanisms responsible for interactions between agents and materials in the limits of complex features, dirty surfaces, and agent impurities is not known. Toward this end, this work was focused on determining whether the use of high-purity agent over- or underestimates decontamination performance results as compared with agent and material configurations that may be observed in operational environments. Results are presented on the characterization of how impurities in agent solutions influence decontamination performance and potential exposure to personnel as compared with high-purity agent, especially for materials susceptible to contaminant absorption.
