摘要
Abstract
The sorption distribution coefficients Kd of plutonium on mudstone and sandstone are studied by batch experiments. The experimental factors influencing Kd are stone granu-larity, the pH value of the aqueous phase, the solid-to-liquid ratio, different ions existing in aqueous phase. It is shown Kd of Pu on mudstone is about 120 mL/g, Kd of Pu on sandstone is 1. 60×104 mL/g. The sandstone has greater sorption ability of Pu than mudstone. It is indicated that the Kd of Pu is increasing while granularity of rock minimizing, pH and ratio of solid and liquid increasing; the sorption of Pu on rocks is strongly in aqueous nitrate solu-tion than simulated groundwater.关键词
