Abstract
The electroremediation method was developed and used for 137Cs release from contaminated soils long time ago. Suspension of soil with suitable electrolyte was electrolyzed at a constant current in special electrolytic cell and the released radiocaesium was separated in the column with caesium specific absorber. The column activity was measured and the decontamination yield during the process was determined. The contaminated soil was obtained from area of the first nuclear power station in the former Czechoslovakia, where it was contaminated in the 70’s and 80’s. In the experiments, the role of voltage, current, electrolyte composition, and temperature in the decontamination process were studied. It is shown that the method allows separating more than 99 % of radiocaesium within 14 h with energy consumption 120–160 Wh g−1.
