This report summarizes efforts to characterize the lewisite contained in recovered munitions and validate a neutralization chemistry for lewisite fill materiel. The selected neutralization reagent, aqueous 20 wt sodium permanganate, was found to be effective in destroying the lewisite. In lab-scale and full-scale Explosive Destruction System testing, the aqueous permanganate consistently produced terminal neutralents that had residual lewisite levels well below the treatment goal of 50 mgL ppm. The reaction products included inorganic pentavalent arsenate and various pentavalent organo-arsenicals. Solid manganese dioxide was also produced during the reaction and was successfully managed in the full-scale Explosive Destruction System testing.
