Abstract
The specification discloses a method for the treatment of particulate material contaminated with polyhalogenated aromatic compounds (PHAs). The method includes vaporizing the PHAs from the material and dissolving the vaporized PHAs in a glycol-based solvent solution. The PHAs are then removed from the solution so that the glycol can be reused.
