Bis-(1,2,4-triazin-3-yl)-1,10-phenanthroline (BTPhen) functionalized magnetic nanoparticles (MNPs), which selectively extract Am(III) over europium(III) from 0.1 M HNO 3 with fast kinetics and a separation factor of 30 have been synthesized. These MNPs also show a small but significant selectivity for Am(III) over Cm(III) with a separation factor of around 3 in 0.1 M HNO 3 . We report also the synthesis of these BTPhen and related ligands via an improved synthetic route bypassing the problematic benzylic oxidation with stoichiometric SeO 2 .

用于分离三价锕系元素和镧系元素的新型 BTPhen 功能化二氧化硅包覆磁性纳米粒子的合成

双-(1,2,4-triazin-3-yl)-1,10-菲咯啉 (BTPhen) 功能化磁性纳米粒子 (MNPs)，可快速从 0.1 M HNO 3 中选择性提取 Am(III) 而不是铕 (III)动力学和 30 的分离因子已被合成。这些 MNP 还显示出对 Am(III) 比 Cm(III) 小但显着的选择性，在 0.1 M HNO 3 中分离因子约为 3。我们还报告了这些 BTPhen 和相关配体的合成，通过改进的合成路线绕过了化学计量 SeO 2 有问题的苄基氧化。
