| 摘 要： | 在不同类型的工业铀矿床的矿石中,吸附状态的铀占了很大的比重,铁钛氢氧化物、硅胶、粘土、有机质等是常见的主要吸附剂。本文利用朗缪尔等温式、弗仑德里奇等温式、D-R等温式,讨论了粘土矿物(主要是高岭土、蒙脱石)对溶液中铀的吸附作用,对吸附作用在铀成矿作用、核废物处置中的意义作了详细的讨论,认为吸附作用是一种重要的成矿作用。

| Abstract: | Uranium as an adsorptive form accounts for a large proportion in the uranium ores of different type economic deposits. A variety of adsorbents including Fe and Ti hydroxides, amorphous silica, clays and organic matter are recognized. Adsorption of U from solutions on clay minerals (kaolinite, montmorillonite) is discussed by using Langmuir, Freundlich and D-R isotherms in this paper. The relationship between U mineralization, nuclear waste disposal and adsorption of U is discussed in detail. It is considered that adsorption is an important mineralization for U and some other deposits (e.g.Au, REE etc). |
