| 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. |
