Abstract
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).
摘要
研究了 BTPhen 配体中 1,10-菲咯啉核的 5 位和 5,6 位溴取代对镧系和锕系阳离子萃取性能的影响。与 C5-BTPhen 相比，BrC5-BTPhen 和 Br2C5-BTPhen 的电子调制使这些配体能够进行精细调整，以提高 Am(III)与 Eu(III)的分离选择性。
