    摘要: As a method of decontaminating a surface covered with a chemical contaminant, a light-absorption agent providing a relatively high neutral density is applied to the surface in intimate contact with the contaminant. Then one or more flashes of high intensity, broad-band frequency, incoherent light is applied to the surface, whereupon, the light-absorption agent converts the absorbed light energy to heat, resulting in vaporization and/or decomposition of the contaminant. The heat generated by the short duration flash is localized at the material on the surface and at a very thin surface layer, and vaporization of the surface material dissipates the heat that is generated, whereby, the surface is substantially unaffected by the process.

    摘要: A new, economical system for removal of persistent reducible organic compounds from aqueous streams by passing the stream, preferably at or near neutral pH, into a bottom inlet to a column to provide fluidization of metal reductant catalyzed to provide efficient and economical reduction or dechlorination of a variety of pesticides and other compounds such as PCB or chloroform. The system is especially useful to reduce the level of soluble, reducible hydrocarbons in very dilute waste streams (1 ppm or less) generally by 99% or more.

    摘要: A process for the destruction of vesicants, nerve agents, and related chemical compounds is described. Blister-type chemical agents such as lewisite and mustards, as well as G or V Class nerve agents and phosphorus-containing pesticides, are reacted with a neutralent solution of a persulfate, preferably potassium peroxymonosulfate, and a peroxide, preferably hydrogen peroxide, at temperatures ranging from ambient to boiling for a time sufficient to reduce the residual agent concentration to levels acceptable for disposal in a routine manner.
