Separation of bismuth from beryllium, lead, iron(III), indium, scandium, lanthanum, antimony(III), zirconium, titanium, thorium, vanadium(V), molybdenum(VI), uranium (VI) and chromium(VI) is achieved by selective extraction of bismuth from 0.1M sodium salicylate solution (adjusted to pH 7) into mesityl oxide (MeO). The extracted species is Bi (HOC(6)H(4)COO)(3).3MeO. The results are accurate within +/- 0.5%, with a standard deviation of 0.8%. The separation and determination of bismuth takes only 15 min.
通过将铋从0.1M水杨酸钠溶液（调节至pH 7）中选择性萃取到异丁基甲酮（MeO）中，实现铋与铍、铅、铁（III）、铟、钪、镧、锑（III）、锆、钛、钍、钒（V）、钼（VI）、铀（VI）和铬（VI）的分离。萃取的物质为Bi (HOC(6)H(4)COO)(3).3MeO。结果的准确度在±0.5%以内，标准偏差为0.8%。铋的分离和测定仅需15分钟。
