Simulants of Chemical Warfare Agents for Tests of Thermal Desorption Technology

Popis výsledku v původním jazyce

Chemical warfare agents (CWA) represent specific toxic species which are still stored, possibly produced and, however, its misuse cannot be excluded, what was proven by number of incidents, recently. Although this potential danger is taken into the account seriously by authorities, usually the security measures focus only on instantaneous reaction on the unwanted situation occurred. Residual solid materials (concrete, masonry, soil, etc.) affected by low volatile CWAs, then, still represent an additional source of potential danger. Such materials should be decontaminated. Thermal desorption technology is an efficient method which can be suggested for cleanup of such materials. According to the above described assumptions, low-volatile agents should be considered as of a great importance. Mainly some nerve agents and vesicants with boiling point between 150 – 300°C fit to assumed parameters. Nevertheless, it is necessary to verify an efficiency of traditional remediation technologies in application on removal of the CWAs. However, from many reasons it is highly required to exclude an experimental work with the real CWAs. Thus, the CWAs must be replaced by harmless chemicals, which, on the other hand, have similar key physical-chemical properties for the purpose of desired experiments. In our contribution, we would like to provide a brief introduction to the topic of CWAs as potential residual contaminants of solid matrixes, and discuss selection of possible simulants for the experimental work. The interaction of CWA simulants with various solid matrixes and problems caused by its hydrolysis will be discussed in experimental part.
