Rb-82 是一种发生器产生的正电子发射同位素 (T-1/2 = 75 s)，越来越多地用于正电子发射断层扫描，以表征心肌灌注。 Rb-82 的母体放射性核素。锶Sr-82。主要是由 > 40 MeV 质子在铷 (Rb-85) 靶上引发的 (p. 4n) 反应产生。在目前的工作中，我们提出了一种新的快速且简单的程序，用于将 Sr-82 与目标分离。基于无机离子交换剂：钾锰矿 MnO2 上铷的选择性吸附。
Rb-82 is a generator produced positron-emitting isotope (T-1/2 = 75 s) that is increasingly being used in positron emission tomography for the characterization of myocardial perfusion. The parent radionuclide of Rb-82. strontium Sr-82. is produced mainly by a (p. 4n) reaction induced by > 40 MeV protons on rubidium (Rb-85) target. In the present work we propose a new fast and simple procedure for Sr-82 separation from the target. based on selective adsorption of rubidium on the inorganic ion-exchanger: cryptomelane MnO2.
