聚合铝对铀(Ⅵ)的吸附
研究了聚合铝对铀的吸附以及在含铝离子的溶液中用偶氮胂Ⅲ进行铀的测定方法的探索。研究表明:在1:1(体积比)的盐酸介质中,当c(A1C13)〈O.1mol/L时,用偶氮胂Ⅲ测定铀误差小于10%,摩尔吸光系数仅10^3L/(mol·cm)。当聚合铝的羟铝比为2、铝浓度为5.64×10^-3mol/L时,可实现铀的吸附率在90%以上。因此聚合铝是一种很好的吸附铀的材料,并可实现含铀废水的减容,从而降低核废物处理成本。...

Bibliography: | This paper investigates the adsorption of uranium on the polyaluminium and the determination of uranium in the solution containing aluminum ion using Arsenazo Ⅲ. Research shows that: the error of uranium determination using Arsenazo Ⅲ is less than 10% when the concentration of aluminum is less than 0.1 mol/L in the 1 : 1 hydrochloric acid medium, molar absorption coefficient is 103 L/(mol · cm). When OH- is two times alumi- num in the polyaluminum and the concentration of aluminum is 5.64 × 10-3 mol/L, the removal rate of uranium can reach 90% or more. Therefore, polyaluminum is a kind of very good uranium adsorption materials, and it can realize the volume reduction of the waste water containing uranium, thus reducing the costs of nuclear waste disposal. polyaluminum uranium; adsorption volume reduction DU Xing-sheng, ZHANG Lin-xi, LIANG Bo, XIE Dong-xiang, SHI Yan-hua, LIU Nian (Jiangxi Nuclear Industry Geological Bureau Testing Center, Nanchang 330002, China) 11-2045/TL |
