摘要
进行了核素 2 38Pu在黄土 -地下水体系中的分配比受液固相相互作用时间、液固比、液相 p H值等因素影响的研究。实验结果表明 ,在 p H值为 8.3时 ,2 38Pu在黄土中 Kd 值可达 1 .89× 1 0 4 m L/g;当液固比在 5 :1～ 2 0 :1 m L/g范围内并逐渐增大时 ,2 38Pu的 Kd
Study was performed of the properties of 238Pu sorption by loess in relation to the effects of contact time, pH value, liquid-to-solid ratio and activity concentrations. The results indicate that Kd value for 238Pu in loess may be as high as 1.89×10 4 mL/g when pH=8.3, and increase with the increase of liquid-to-solid ratio within the range of 5∶1～20∶1 mL/g.
