Abstract:
Process parameters have been developed which permit purification of wastewaters containing dissolved TNT, RDX, or nitroglycerin by treating the wastewater with a surfactant of the quaternary amine type at a pH of about 11.5. With TNT, the surfactant forms a precipitate that is removed by filtration. The other explosives, if present, are removed by hydrolysis. This reaction is accelerated by the surfactant. Nitroguanidine is unaffected by the surfactant treatment, but can be destroyed by contact with an ion exchange resin. The methods of analysis are described for RDX and TNT in pink water and for nitroglycerin and nitroguanidine in other wastewaters. The recommended process for pilot plant operation is also described.
