通过89 Y（9 Be，xn）93，94，95 Tc反应首次制备了富质子Tc放射性核素。为了优化所选特定放射性核素的产率，在不同的入射能量下，使用叠箔技术和离线γ谱法测量了93 Tc、94 Tc和95 Tc的批量产率。用液-液萃取（LLX）和固-液萃取（SLX）技术从钇中分离出无载体添加的~（93）、~（94）、~（95）Tc放射性核素。在HCl存在下，在LLX中使用在环己烷中稀释的三辛胺（TOA）作为液体阴离子交换剂。在HCl介质中，分别使用阳离子和阴离子交换树脂DOWEX-50和DOWEX-1进行SLX。
Abstract Proton rich Tc radionuclides have been produced for the first time through 89Y(9Be, xn)93,94,95Tc reactions. In order to optimize the yield of a particular radionuclide of choice, batch yield of 93Tc, 94Tc and 95Tc have been measured at different incident energies using stacked-foil technique followed by off-line γ-spectrometry. No-carrier-added (nca) 93,94,95Tc radionuclides have been separated from bulk yttrium by liquid–liquid extraction (LLX) and solid–liquid extraction (SLX) techniques. Trioctylamine (TOA) diluted in cyclohexane was used as liquid anion exchanger in LLX in presence of HCl. SLX was carried out using cation and anion exchanger resin, DOWEX-50 and DOWEX-1, respectively, in HCl medium.
