建立了一种阴离子交换法分离硒和砷，在72se /72As发生器中具有潜在的应用价值。子72a与母体72se的分离是基于两个氧阴离子在其最高氧化态下的相对酸碱行为。在pH为1.5时，硒酸盐以HSeO4−和SeO42−的形式保留在强碱性阴离子交换树脂上，而中性砷酸H3AsO4则被洗脱。
An anion exchange method was developed to separate selenium and arsenic for potential utility in a72Se/72As generator. The separation of the daughter72As from the72Se parent is based on the relative acid–base behavior of the two oxo-anions in their highest oxidation states. At pH 1.5, selenate is retained on strongly basic anion exchange resin as HSeO4−and SeO42−, while neutral arsenic acid, H3AsO4, is eluted.
