| 英文摘要 | The liquid-liquid extraction behavior of short-lived molybdenum and tungsten isotopes from HCl and HNO(3) as well as HF/HNO(3) acid media was studied using the alpha-benzoinoxime/chloroform system. The goal of the present experiments was to find an extraction system with a high selectivity for the group 6 elements in the periodic table which is suitable for the study the Solution chemistry of seaborgium (Z = 106). It was found that Mo and W are both effectively extracted using alpha-benzoinoxime as an extractant and the maximum extraction yield is 100% and 94% for Mo and W, respectively. Ions of MO(2)(2+) (M = Mo, W) exist in HCl between the concentration range of 0.1-3 M and can be extracted quantitatively into the organic phase. The decrease of extraction yields at lower or higher acid concentration is due to the formation of anionic Species MO(4)(2-) or MO(2)Cl(3)(-). The extraction behavior of Mo and W in HNO(3) solution is similar to that in HCl solution. In HNO(3)/HF mixed acid solutions, due to the formation of MO(2)F(3)(-) a decrease of extraction yield at higher HF concentration, similar to the case of HCl is observed. The extraction equilibrium is reached within 10-30 s, which means the extraction kinetics of alpha-benzoinoxime/chloroform extraction system is fast enough for the study of the isotope (265)Sg. The extraction behavior of molybdenum and tungsten shows a distinct difference in the range of 0.05 to 0.2 M HF with 1 M HNO(3). This shows that differences in the complexation with fluoride ion exist in Mo and W. This Study focuses on the investigation of the tendency of group 6 element for complexation with fluoride ion. |
