Life protection from air pollutants occupies the interest of the leaderships in the military forces. The main sources of pollutants are the mass destructive weapons (MDW) which include nuclear, biological, and chemical weapons (NBC). The popular technique used in air purification is the adsorption of chemical warfare agent (CWA) vapors on the surface of a solid sorbent, such as, charcoal granules. Another technique that increasingly took place in the last several years is the catalytic oxidation of the CWA in a catalytic reactor which is the subject of this research. The objective of this experimental work is to study the catalytic oxidation of toxic warfare agents which are represented as organic halids.1-2 Dichloroethane (DCE) is used as an imitator for the warfare agents which investigated over V2O5/TiO2- based catalyst. The destruction of 1,2 DCE strongly depends on catalyst temperature and concentration of 1,2 DCE. The experiments were carried out at different catalyst temperatures 350, 390 and 450C , and different concentration of 58.9 mg/l, 47.9 mg/l and 28.4 mg/l. The highest conversion ratio (78.75 %) was obtained for initial concentration of 28.4 mg/l and
catalyst temperature of 450C.
