46.0 MeV alpha particle induced reaction on gallium oxide target results production of no-carrier-added (NCA) ^71,72As and ⁶⁷Ga tracer. ^71,72As were separated from the target matrix by solid liquid extraction (SLX) using two different exchangers, Dowex-1 and Dowex-50. At best condition of 0.2 g Dowex-1 + 6 M HCl and 0.2 g Dowex-50 + 10⁻³ M HCl bulk gallium was completely extracted leaving behind NCA ^71,72As in the aqueous phase. Dowex-50 was found to be more suitable and offered high separation factor, 3.2 × 10⁵.

通过固体阳离子和阴离子交换剂 DOWEX-50 和 DOWEX-1 从 α 粒子诱导的氧化镓靶中分离 71,72As

46.0 MeV α 粒子在氧化镓靶上引起的反应产生无载流子添加 (NCA) ^71,72 As 和⁶⁷ Ga 示踪剂。^71,72使用两种不同的交换器 Dowex-1 和 Dowex-50 通过固液萃取 (SLX) 从目标基质中分离出砷。在 0.2 g Dowex-1 + 6 M HCl 和 0.2 g Dowex-50 + 10 ^-3  M HCl 大体积镓的最佳条件下被完全萃取，在水相中留下 NCA ^71,72 As。Dowex-50 被发现更合适，并提供高分离因子，3.2 × 10 ⁵。
