| Popis: |
Efficient decontamination of 137Cs in electric arc furnace dust (EAFD) was carried out using a solid-liquid extraction method and then the obtained wastewater contaminated with 137Cs was treated by a co-precipitation. The influences of pH, stirring time, settling time, and different radioactivity on removal efficiency were assessed. Depended on the initial concentration and the solid-liquid ratio, it is possible to reduce around 93–96% radioactivity from EAFD, meanwhile the removal efficiency of 137Cs from wastewater exhibits in excess of 99%. After treatment, the final solution was certified safe from 137Cs, while the radioactive sludge could be stored safely. |
