||The process of microwave plasma detoxification has been applied successfully to the destruction/disposal of a U.S. Navy red dye pyrotechnic smoke mixture. The mixture was added as a powder, a solvent solution, and a water slurry. Material balance for detoxification of the slurry indicated that less than 0.20 percent solids were found beyond the reaction zone, or 99.8+ percent conversion to gaseous products. Analysis by spectrophotometry in the visible region indicated little or no dye starting materials (less than 5 ppm) in the residue. Ultraviolet fluorescence, UV spectrophotometry, and gas chromotography/mass spectrometry indicated the presence of less than 2 ppm carcinogenic polyaromatic hydrocarbons (PAH). Since PAH has been found in air oxidation products derived from these materials, a significant advantage would appear to derive from the plasma process. During the study, several vacuum feed techniques were evaluated with a view toward their utilization in forthcoming pilot equipment tests. Especially with high solids slurries and solutions, where non-Newtonian flow can cause difficulties when gravity feed methods are used, it will be necessary to use positive displacement methods to obtain uniformity and reproducibility during the addition process.
