Abstract

This paper deals with the development and application of the technologies for the de-contamination of soils polluted by organic substances, namely polychlorinated- biphenyls (PCB). The results from the operation of the semi-pilot and large-scale units aimed at the disposal (elimination) of PCB are reported in soils and solid waste by a thermal de-sorption in inert atmosphere, in soils and contaminated solid waste through extraction and washing by a water solution of surface-active substances, and in organic liquids and oils by a chemical reaction of PCB with a suspension of elementary sodium. The paper also mentions the effectivity of the chemical method of the decomposition of PCB in wastewater in the presence of hydrogen peroxide, by exposing it to UV r
