摘　　要：随着原子能事业、工矿业等的发展,由放射性核素铀引发的环境污染问题日趋严峻,粘土矿物吸附法被广泛运用于处理低浓度铀放射性污染。由于粘土矿物的自身特性、储量丰富等特点,使得其不仅为找矿提供依据,也是治理环境污染的优选材料,尤其是作为经济、高效的吸附材料。但是影响粘土矿物吸附铀的因素错综复杂。从粘土矿物特性、铀化学性质、铀赋存形式等几方面阐述了表生环境中粘土矿物吸附铀的影响因素,以期为铀矿勘探、铀的提取提供理论支撑,也为处理放射性污染提供依据。With the development of uranium mining, metallurgy and nuclear industry, the pollution of radioactive nuclide uranium is more and more serious. Clay minerals adsorption method is widely used to deal with radioactive pollution of low concentration uranium. Because of its characteristics and abundant reserves, clay minerals can not only provide the basis for ore prospecting,but also be the preferred materials for environmental pollution control,especially as an economical and efficient adsorbent. The factors influencing the adsorption of uranium on clay minerals from the aspects of clay mineral characteristics,chemical properties and uranium occurrence were expounded. It could provide theoretical support and basis for the extraction of uranium exploration, extraction of uranium and the treatment of radioactivepollution.
