The preliminary results presented here show that gamma-irradiation of ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([C4mim][PF6]) markedly decreases Sr2+ partitioning in the crown ether/[C4mim][PF6] extraction phase due to the competition between radiation-generated H+ and Sr2+ to interact with the crown ether, however, washing irradiated [C4mim][PF6] with water gives a simple way of recycling the ionic liquid.
此处展示的初步结果表明,对离子液体1-丁基-3-甲基咪唑鎓六氟磷酸盐([C4mim][PF6])进行γ辐照,会显著降低冠醚/[C4mim][PF6]萃取相中Sr2+的分配,这是由于辐射产生的H+与Sr2+之间存在与冠醚相互作用的竞争;然而,用水洗涤辐照后的[C4mim][PF6]提供了一种回收该离子液体的简单方法。
