铀在北山花岗岩中的吸附迁移影响因素研究
Investigation of Sorption and Migration Effect Factors of Uranium on Granites in Beishan
摘要
Abstract
The paper simulates and predicts the conditions after the uranium entered into the groundwater in a disposal site of pre-selected high level radioactive waste in China by using hydrologic modeling software PHREEQC- Ⅱ. The paper also analyzes the different roles of the various influential factors such as pH, dispersi-ty, diffusion coefficient and temperature in the simulation. The behaviors of sorption and migration of uranium on granites in Beishan have been investigated by using the batch method. The distribution coefficient of uranium is determined. The effects of granite particle size, pH, concentration and temperature of uranium in simulated groundwater are studied. The results show that the ability of granites in Beishan to adsorb uranium is rather weak and influenced by some influential factors. The results of simulation by software is similar to the experimental results. Therefore, the study will provide an important basis for the safety research on the site.关键词
