A study on the evaluation of cesium removal performance in soil washing process using flocculating agent

As a result of nuclear power plant accidents such as Chernobyl and Fukushima, and even their maintenance, the soil is contaminated due to the discharge of radioactive materials. Soil contaminated by Cs and other radioactive materials must be decontaminated so that the land can be reused as an industrial site or at least restored to a natural state. Accordingly, this study selected the soil washing method from among several available. In this study, water is used as a washing agent for the soil washing process while a flocculating agent is added to increase efficiency. It was found that when the flocculating agent was used, maximum removal rate being about 88%. (author)
