Box 275(26) Beijing 102413, China; 2 Beijing Institute of Nuclear Engineering, Beijing 100840, ChinaAbstract The studies of facts effecting on stripping Np from organic phase with HNO 3 and the determinations of Np in the stripping extractor with the reducer of n butyraldehyde are carried out.
单级实验结果表明,正丁醛的加入和延长正丁醛与镎的相互作用时间,有利于从有机相中反萃镎;正丁醛的加入对铀、钚分配比的影响不大;但铀浓度增加会增加镎的反萃。

She assumptions Road: Emilio segre should have found the first transuranic element neptunium, if he is not a lack of adequate knowledge of chemical and rare earth elements to make mistakes to 23,993 words; Similarly, Enrico Fermi should have been found in fission, if his team The chemical separation technology is not quite so appropriate.
她假设道:Emilio segre本应当发现第一个超铀元素镎,如果他不是缺少足够的化学知识而把23993错认作稀土元素的话;与此相似,Enrico Fermi本应该发现裂变,如果他的研究小组的化学分离技术不是这样不甚适当的话。
-
All the methods used now have a common technical difficulty: The presence of large amount of uranium makes unacceptable interferences to the determination of neptunium. A separation procedure is absolutely necessary to separate neptunium from uranium completely.
国内一直没有一个比较理想的准确、灵敏的方法,解决铀产品中微量镎的测定问题,主要原因是现有的方法存在一个共同的技术难点:常量的铀对微量镎的测定干扰很大,必须要将常量铀与微量镎定量分离。

The adsorption isotherm of neptunium on silica gel correspond to the form of Langmuir isotherm. According to Clausius-Claperon equation,from the slope in InKd vs 1/T plot,adsorption heat could be estimated. From the data of adsorption heat it is concluded that the adsorption of neptunium on silica gel in nitric acid solutions belongs to chemical adsorption and the adsorption process is an endothermic reaction.
三种价态的镎在硅胶上吸附的等温线符合兰格缪尔吸附等温线的形式,是单分子层吸附;根据克劳修斯-克拉柏龙方程,以1nKd对1/T作图,通过直线斜率计算出吸附热,从吸附热的数据可判断三种价态的镎在硅胶上的吸附属于化学吸附,是吸热的过程;对NpOV)、Np和Np(VD在硅胶上的吸附进行了比较,提出了三种价态的锋在硅胶上吸附的机理。
