  • 摘要: 受天然铀矿物形成条件的启发,通过改变含铀废液的物理化学条件,即能在含铀废液中形成较稳定沥青铀矿或者其他沉淀物,实现除铀目的。这种除铀方法被定义为沥青铀矿结晶法。在不同的物理化学条件下采用此方法处理了含铀废液,其结果表明,升高温度、降低Eh,除铀速度加快,除铀效率提高,其中,在物理化学条件为T=85℃、pH=3、Eh=+61.1 mV时,铀元素以沥青铀矿的形式从溶液中析出,除铀率高达99.6%,效果良好。
    Abstract: This paper presents the uraninite crystallization method, a new method for uranium-bearing wastewater treatment, on the basis of the forming conditions of natural uranium ores.It achieves the purpose of removing uranium through the formation of uraninite in the uranium-bearing wastewater by changing whose's physicochemical conditions.Applying the method in the uranium-bearing wastewater treatment under various physicochemical conditions, the results show that the uranium removing speed and rate rise with the increase of temperature and reducibility (i.e.the decrease of Eh value).When T=85 ℃, pH=3, and Eh=+61.1 mV, uraninite will be separated from the solution in 1.5 h with a precipitation rate as high as 99.6%, achieving a satisfactory uranium removal effect.
