摘要

采用透扩散实验研究了Sr、I和Pu在花岗岩中的扩散行为。测定了26℃时Sr、I和Pu在花岗岩中的有效扩散系数分别为(1.24±0.03)×10-13 m2/s、(2.88±0.02)×10-13 m2/s和(1.33±0.52)×10-13 m2/s。元素的形态和分布对其扩散行为有显著影响。

Diffusivity of Sr,I and Pu in Granite With Through-Diffusion Experiment

The diffusion behavior of Sr,I and Pu in granite was investigated by throughdiffusion experiment.The effective diffusion coefficients of Sr,I and Pu in granite at 26℃ were determined to be(1.24±0.03)×10-13 m2/s,(2.88±0.02)×10-13 m2/s and(1.33± 0.52)×10-13 m2/s,respectively.It is also observed that the speciation and species distribution of element have significant effects on its diffusion behavior.
