No-carrier-added (NCA) 71,72 As radionuclides were produced by irradiating gallium oxide target by 46 MeV α -particles. NCA 71,72 As was separated from the target matrix by liquid-liquid extraction (LLX) using trioctyl amine (TOA) and tricaprylmethylammonium chloride (aliquat-336) diluted in cyclohexane. The bulk gallium was quantitatively extracted into the organic phase leaving 71,72 As in the aqueous phase. Complete separation was observed at 3 M HCl + 0.1 M TOA and 2 M HCl + 0.01 M aliquat-336.

从46 MeVα粒子辐照的氧化镓靶标中分离出未添加载流子的71.72As

无载体添加（NCA）71.72作为放射性核素，是通过用46 MeVα-粒子辐照氧化镓靶而产生的。使用三辛胺（TOA）和在环己烷中稀释的三辛基甲基氯化铵（aliquat-336）通过液-液萃取（LLX）从目标基质中分离出NCA 71.72 As。大量的镓被定量萃取到有机相中，在水相中留下71.72As。在3 M HCl + 0.1 M TOA和2 M HCl + 0.01 M aliquat-336溶液中观察到完全分离。
