ABSTRACT:
Heavy metals are removed from waste lubricating oil by heating in the presence of an oxidation catalyst and a free radical initiator at temperatures in the range of about 150.degree.-200.degree. C. Corrosion and oxidation inhibitors previously added to the oil are thereby oxidized to form a separable sludge which contains the bulk of heavy metal contamination. The process is of particular advantage in removing contaminating radioactive nuclides from lubricating oils used in nuclear generating facilities.
