Effects of bromine substitution at the 5 and 5,6-positions of the 1,10-phenanthroline nucleus of BTPhen ligand on their extraction properties for Ln(III) and An(III) cations have been studied. Compared to C5-BTPhen, electronic modulation in BrC5-BTPhen and Br2C5-BTPhen enabled these ligands to be fine-tuned in order to enhance the separation selectivity of Am(III) from Eu(III).
研究了 BTPhen 配体的 1,10-菲罗啉核的 5 和 5,6 位溴取代对其萃取 Ln(III) 和 An(III) 阳离子特性的影响。与 C5-BTPhen 相比,BrC5-BTPhen 和 Br2C5-BTPhen 中的电子调制使这些配体能够进行微调,以提高 Am(III) 与 Eu(III) 的分离选择性。
