ABSTRACT:
Polyhalogenated biphenyls such as PCB's, contained in transformer or capacitor oils, are removed from the transformer or capacitor oils by means of a combustible adsorbent which selectively adsorbs polyhalogenated biphenyls from transformer oils and the like. The adsorbent containing the adsorbed polyhalogenated biphenyls and the polyhalogenated biphenyls adsorbed thereon are destroyed by combustion in a molten salt.
