Abstract

There is disclosed a process for destroying halogenated hydrocarbons such as PCBs and PCBs in PCB containing fluids (e.g., Askarel) and oils (e.g., paraffin oil, transformer oil, etc.) at ambient temperature. The process comprises reacting halogenated hydrocarbons, such as PCB containing fluids or oils with a solid oxidant in the presence of a concentrated acid. Preferably, the solid oxidant is potassium permanganate and the concentrated acid is sulfuric acid. Destruction efficiency is as high as 99.95%.
