近年来,放射性溴同位素的研制愈来愈得到重视.这是因为,与碘相比,溴-碳键较碘-碳键更为牢固,故溴的标记物也较为稳定。但直至目前,溴的放化分离通常仍采用干馏、蒸馏、共沉淀等方法,工艺流程繁杂,且分离效果也不尽满意。 选择性吸附色层分离方法具有许多独特的优点,国内外学者相继研究过用铜基铂选择性吸附分离碘的方法,但对溴的研究尚未见报道。
In recent years, the development of radioactive bromine isotopes has gained more and more attention, because bromine-carbon bonds are more stable than iodine-carbon bonds compared with iodine, so bromine markers are also relatively stable. However, up to now, the methods of radiochemical separation and purification of bromine are usually still using methods such as carbonization, distillation and coprecipitation. The process flow is complicated and the separation effect is not satisfactory. Selective adsorption chromatographic separation has many unique advantages. Domestic and foreign scholars have studied the selective adsorption and separation of iodine using copper-based platinum, but the research on bromine has not been reported yet.
