摘要
Abstract
The distribution coefficients of Pu(Ⅳ ) and Pu( Ⅴ ) between aeolian sand, sandy soil, or gravel soil and water, and of Pu(Ⅴ ) between iron or iron oxides and water were determined with batch experiments. Various factors that affect the plutonium sorption were examined, including the soil composition, the oxidation state of Pu, and the method for preparation of Pu spike solutions. The sorption of Pu(Ⅳ) in soil is found more stronger than that of Pu( Ⅴ ). Their distribution coefficients in clayey silt are in the range of 103-104 mL/g, while those of Pu( Ⅴ ) in iron oxides reach as high as 105-106 mL/g. A higher clay content in clayey silt favarites the sorption of plutonium. The method for preparation of Pu spike solutions also influences the distribution coefficient of plutonium even all other experimental conditions are kept unchanged.关键词
