在298 K下，研究了在0.1 ~ 11.2 M（M = mol/dm ~ 3）HCl溶液中，用包埋在高孔硅珠中的苯并咪唑型阴离子交换树脂对Mo（VI）物种的同位素分馏。结果表明，Mo（VI）物种的斜率系数与吸附过程中吸附物-吸附质相对亲和力参数b值之间存在良好的线性关系，并利用Mo（VI）物种的同位素分馏曲线得到了Mo（VI）物种的同位素分馏系数。
The isotope fractionation of Mo(VI) species using benzimidazole-type anion-exchange resins embedded in high-porous silica beads was investigated in various HCl solutions ranging in concentration from 0.1 to 11.2 M (M = mol/dm3) at 298 K. As a result, the plots of the slope coefficients of Mo(VI) species against the correspondingbvalues, which are parameter of the adsorbent–adsorbate relative affinity in the adsorption process, were found to be a good linear relationship and the isotope fractionation coefficients of Mo(VI) species were also obtained by using the isotope fractionation curve of Mo(VI) species.
