Several passive biosorption mechanisms of uranium such as complexation,redox,microprecipitation and ion exchange are discussed,and the trend of development is forecasted.

探讨了生物对铀的被动吸附机理,论述了其表面配合、氧化、机沉子交换等过程,并进行了展望。

The new methods mainly contain the adsorption of natural materials, modification materials, humic acids, biosorption, quod of silicon micro encapsulization and nanotechnology.

主要包括天然材料、改性材料的吸附,生物吸附,硅囊技术和纳米技术等。
