This report summarizes efforts to select and validate a cleaning reagent to be used in demilitarization operations. In demilitarization operations involving the chemical neutralization of arsenic-containing chemical warfare agents with sodium permanganate, the equipment becomes coated with deposits which are primarily manganese dioxide. These deposits must be removed from the equipment on a regular basis to prevent leaks and maintain operational tempo. An oxidative aqueous-based reagent identified as HPO2(tm) reagent ...

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 mg/L (ppm). The reaction ...

The purpose of this work was to select, optimize, and validate a reagent for neutralization of arsenical fills contained in WWII era non-stockpile munitions. The work focused on the neutralization of arsinol, a mixture of diphenylchloroarsine (DA), phenyldichloroarsine (PD), triphenylarsine (TPA), and arsenic trichloride.
