| 1 | Electrochemical extraction of cerium and formation of Al–Ce alloy from CeO_2 assisted by AlCl_3 in LiCl–KCl melts显示文摘This work presents an electrochemical extraction of cerium and synthesization of Al–Ce alloy in LiCl–KCl melts on Mo and Al electrodes by chlorination of CeO2 using AlCl3 at 873 K. The cyclic voltammogram on Mo electrodes in LiCl–KCl–CeO2 melt showed no obvious reduction wave other than the reduction of Li(I). After the addition of AlCl3, the signals of the reaction of Ce(ⅡI)/Ce(0) and the synthesization of Al–Ce and Al–Li alloys were investigated by cyclic voltammetry, square-wave voltammetry, open-circuit chronopotentiometry and chronopotentiometry. These results indicated that AlCl3 can chloridize CeO2 and that it is possible to extract cerium and form Al–Ce and Al–Li–Ce alloys in LiCl–KCl–CeO2–AlCl3 melts. According to potentiostatic electrolysis, only the Al4 Ce layer coated the Al electrodes. According to galvanostatic electrolysis, Al–Ce(Al4Ce, Al3 Ce, and Al92Ce8), Al2Li3, and Al phases were formed on Mo electrodes, and the content of cerium in the Al–Li–Ce alloys was more than 17 wt%. | ZHANG Meng WANG HaoYu HAN Wei ZHANG MiLin LI YunNa WANG YanLi XUE Yun MA FuQiu ZHANG XingMei | 2014 | Science China Chemistry2014，57，11： | 2 |

| 3 | Study on Coordination of Amidoxime Small Molecule Ligand with Uranyl Ion under Seawater Condition显示文摘It has been found that uranium concentration in seawater is consistent in various locations around the world,even at depths up to 5 000 feet,at 3 parts per billion(ppb).With constant uranium concentration of 3ppb in a total of 1.3×1022 liters of seawater,the estimated amount of uranium is about 4billion tons in the ocean,and uranium exists mainly in U(Ⅵ)oxidation state as uranyl carbonates,about 98%. | LIU Tingting TIAN Guoxin YANG Suliang LIU Qian MA Fuqiu XUE Yun | 2018 | 中国原子能科学研究院年报2018，，1： | 0 |
| 4 | Electroextraction of neodymium from LiCl-KCl melt using binary liquid Ga-Al cathode显示文摘The electrochemical behaviour of Nd(Ⅲ)ion was investigated on inert W,active Ga and Ga-AI cathodes.It is established that the reduction of Nd(Ⅲ)ion on the inert electrode is a consecutive two-step process while that on the active electrodes is a one-step process.The apparent standard potential of the Nd(Ⅲ)/Nd redox couple at different temperatures was determined by open-circuit chronopotentiometry and semi-differential method,and the relationship between temperature and apparent standard potential was further discussed.The thermodynamic properties of Nd in Ga and Ga-Al electrodes such as activity coefficient and activity were evaluated via intermittent coulomb titration and temperature dependence test,and the effect of temperature on activity coefficient was verified.Finally,Nd was successfully extracted in form of alloy from molten salt by galvanostatic electrolysis,in which the current efficiency of91.7%for the electroextraction indicates that the binary liquid Ga-Al electrode has favorable performance. | Li Ding Xuepeng Wang Yongde Yan Valeri Smolenski Wenda Xu Alena Novoselova Yun Xue Fuqiu Ma Xingmei Zhang | 2023 | Journal of Rare Earths2023，41，8： | 0 |
