 note = {By the standard soil washing methods, only the coarse grained soils can be washed and  reused. Contaminants adsorbed to the soil surface cannot be removed in the fine-grained  soils. A new washing technology was proposed that utilizes a washing solution  containing an ion exchange substance and freeze-thaw phenomena for ion exchange on  the surface of soil particles. In this study, potassium was used as an alternative substance  of a radioactive cesium and an ammonium acetate solution was used as washing solution  of an ion exchange substance. The purpose of this study is to clarify the effect of washing  condition on the remediation. One-dimensional freeze thaw tests were performed using  samples mixed with water or ammonium acetate solution. In the experimental results,  the concentration of potassium in the thaw drainage was greater ammonium acetate  solution mixing sample than water mixing one. Therefore, the washing efficiency of the  tests using a specimen mixed with ammonium acetate solution was greater than that  mixed with water. It was indicated that potassium is desorbed before freezing because  of the specimen mixed with ammonium acetate solution.},
