METHOD FOR DECONTAMINATING SURFACES OF SOLID BODIES FROM INORGANIC POLLUTANTS INCLUDING RADIOACTIVE ONES Russian patent published in 2000 - IPC

Abstract RU 2153203 C2

FIELD: supercritical extraction of metals. SUBSTANCE: method involves metal extraction by supercritical carbon dioxide containing beta-dicarbonyl compound and water; supercritical gas is doped with organic amine which enables reducing beta-dicarbonyl consumption by 50-100 times compared with known methods. Method provides for extraction of polluting metals of all chemical forms including salts, oxyls, and the like. EFFECT: enlarged functional capabilities. 2 cl
