| 1 | Efficacious selective separation of U(Ⅵ) over Mo(Ⅵ) using novel 2,9-diamide-1,10-phenanthroline ligands: Liquid-liquid extraction and coordination chemistry显示文摘Uranium and molybdenum are important strategic elements. The production of ^(99)Mo and the hydrometallurgical process of uranium ore face difficult problems of separation of uranium and molybdenum.In this study, the four phenanthroline diamide ligands were synthesized, and extraction and stripping experiments were performed under different conditions to evaluate the potential application of these ligands for separation of U(Ⅵ) over Mo(Ⅵ). With the growth of alkyl chain, the solubility of ligands could be greatly improved, and the separation effect of U(Ⅵ) over Mo(Ⅵ) gradually increased. The SF_(U/Mo) were around 10,000 at 4 mol/L HNO3. Three stripping agents were tested with the stripping efficiency of Na_(2)CO_(3)(5%) > H_(2)O > HNO_(3)(0.01 mol/L). The stripping percentages of the three stripping agents were all close to unity, indicating that the ligands had the potential to be recycled. The chemical stoichiometry of U(Ⅵ) complexes with ligands was evaluated as 1:1 using electrospray ionization mass spectrometry,ultraviolet visible spectroscopy and single-crystal X-ray diffraction. The consistency between theoretical calculation and experimental results further explains the coordination mechanism. | Taoyuan Xiu Simei Zhang Peng Ren Siyan Liu Shuai Wang Hamza Shehzad Jingyang Wang Meng Zhang Guoan Ye Caishan Jiao Qunyan Wu Liyong Yuan Zhifang Chai Weiqun Shi | 2023 | Chinese Chemical Letters2023，34，11： | 1 |

| 9 | Experimental and Computational Research on Single-stage Reduction Stripping of Pu(Ⅳ) with U(Ⅳ)显示文摘The single-stage reduction stripping of Pu(Ⅳ)from 30%TBP/n-dodecane was studied using U(Ⅳ)as reducing agent.The effects of phase contact time,reducing agent concentration,acidity and supporting reducing agent concentration on the stripping rate of Pu(Ⅳ)were investigated.The single-stage stripping experiment was carried out in a glass centrifugal tube.The Pu(Ⅳ)containing organic solution and the U(Ⅳ)containing reduction stripping solution of aqueous phase was added into the centrifugal tube in a 1∶1ratio.At room temperature,the oscillator was used to oscillate to a predetermined time,and then the two phases were centrifuged rapidly. | HUANG Xiaohong YU Ting HE Hui YE Guoan LIU Zhanyuan LI Fengfeng TANG Hongbin | 2018 | 中国原子能科学研究院年报2018，，1： | 0 |
| 10 | Study on Mathematical Model of Single-stage Reductive Stripping of Pu(Ⅳ) with U(Ⅳ)显示文摘The uranium-plutonium separation process unit(1B)in the Purex process is the watershed of the whole process,and its operating conditions have an important influence on the subsequent process units.The uranium-plutonium separation process is to reduce Pu(Ⅳ)to Pu(Ⅲ)by using appropriate reducing agents.Since the low distribution coefficient of Pu(Ⅲ)in the organic phase(30%TBP/kerosene),plutonium is rarely extracted by the organic phase.Therefore,the plutonium is stripped into the aqueous phase,and U(Ⅵ)continues to be retained in the organic phase to achieve uranium plutonium separation.U(Ⅳ)is the reducing agent of the uraniumplutonium separation process unit in the Purex process and the reductive and stripping process is shown in Fig.1. | YU Ting HE Hui YE Guoan LIU Yuekun TANG Hongbin | 2018 | 中国原子能科学研究院年报2018，，1： | 0 |
| 11 | Study on Mathematical Model of Single-stage Reductive Stripping of Pu(Ⅳ) with HAN显示文摘Hydroxyl nitrate(HAN)is a reducing agent for plutonium purification unit(2B)in the Purex process.HAN is helpful to minimize the volume of solid waste and avoid the plutonium loss and the corrosion of stainless steel facilities as an organic salt-free reducing agent.The reduction and stripping process of Pu(Ⅳ)is to reduce Pu(Ⅳ)by HAN to trivalent species,which is not easily extracted by organic phase,and can be extracted back from the organic phase to the aqueous phase.This is a dynamic process,which involves the chemical reactions of the reduction of Pu(Ⅳ),and the distribution equilibrium of the components Pu(Ⅳ)and Pu(Ⅲ)in the two-phase extraction. | LIU Yuekun YU Ting YE Guoan HE Hui LAN Tian TANG Hongbin | 2018 | 中国原子能科学研究院年报2018，，1： | 0 |
