在铀的裂变过程中,形成了一系列的锑放射性同位素,其质量数从125到134。但是,在长时间放量的裂变产物溶液中只存在有Sb~(125)(半衰期2.6±0.1年)。核裂变现象发现不久,阿白尔逊(Abelson)就发现裂变产物中有放射性锑。他应用的分析方法是在4N硫酸中用金属锌还原锑,生成气态的锑化氮而蒸馏分离。由于其程序的化学产额很低(只有10%),此法以后很少有人应用。拉鞭鲁欣娜(Лаврухина)对此法作了很大的改进,在75%(体积)的盐酸溶液中用金属锌还原,蒸馏一小时得到92%的回收率。
During the fission of uranium, a series of antimony radioisotopes were formed, ranging in mass from 125 to 134. However, only Sb 125 (half-life 2.6 ± 0.1 year) was present in the long-lived fission product solution. Shortly after the discovery of the fission phenomenon, Abelson discovered radioactive antimony in the fission products. His application of analytical methods is the use of 4S sulfuric acid metal zinc reduction of antimony, the formation of gaseous stibium nitrogen and distillation separation. Due to the low chemical yield of its program (only 10%), this method is rarely used. This method has been greatly improved by the method of Лаврухина, which is reduced with metallic zinc in 75% by volume hydrochloric acid solution and distilled for one hour to give a 92% recovery.
