铀水冶生产过程巾产生一定的废物,其中的放射性核素能对地表水和地下水构成长期潜在危害。微生物对铀的吸附作用可用于降低水中铀的浓度达到环境保护的目的。探讨了微生物对铀的被动吸附机理,论述了其表面配合、氧化还原、无机微沉淀及离子交换等过程,并进行了展望。
Some wastes have been produced in the uranium hydrometallurgy process, and the radionuclide in the wastes has long-term potential harms to the surface water and groundwater. The concentration of uranium in solution can be decreased effectively by biosorption of uranium. Several passive biosorption mechanisms of nranium such as complexation, redox, microprecipitation and ion exchange are discussed, and the trend of development is forecasted.
