چکیده انگلیسی
800Â L washing-electrokinetic soil separation equipment was manufactured to decontaminate uranium contaminated soils from Korean nuclear facilities. For the removal of uranium at more than 95% from radioactive soil through soil washing-electrokinetic technology, several decontamination experiments were carried out. For a reduction of the generation of large quantities of metal oxides in a cathode, a pH controller is used to control the pH of the electrolyte solution between 0.5 and 1.0 for the formation of UO2+. More than 60% metal oxides were removed through pre-washing, an electrolyte solution was circulated by a pump, and a metal oxide separator filtered the metal oxide particles. 60-65% of the uranium was removed from the soil by soil washing as a part of the pre-treatment. When the initial 238U concentration of the soil was 22.2Â Bq/g, the required electrokinetic separation time for the removal of below the clearance 238U concentration of 0.4Â Bq/g was 35Â days, and the generated electrolyte solution rate was 1.4Â ml/g. When the initial concentration of 238U in the soil was higher, a longer decontamination time was needed, but the removal rate of 238U from the soil was higher.
