Abstract

Effects of chloro and bromo substitution at the 4-position of the pyridine ring of 6,6'-bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydrobenzo[e][1,2,4]triazin-3-yl)-2,2'-bipyridine (CyMe-BTBP) have been studied with regard to the extraction of Am(III) from Eu(III) and Cm(III) from 0.1-3 M HNO. Similarly to CyMe-BTBP, a highly efficient (D > 10 at 3 M HNO) and selective (SF > 100 at 3 M HNO) extraction was observed for Cl-CyMe-BTBP and Br-CyMe-BTBP in 1-octanol but in the absence of a phase-transfer agent.

摘要

研究了 6,6′-双（5,5,8,8-四甲基-5,6,7,8-四氢苯并[e][1,2,4]三嗪-3-基）-2,2′-联吡啶（CyMe-BTBP）中吡啶环 4 位的氯和溴取代基对 Am(III)从 Eu(III)和 Cm(III)从 0.1-3 M HNO 中萃取的影响。与 CyMe-BTBP 类似，在 1-辛醇中，Cl-CyMe-BTBP 和 Br-CyMe-BTBP 即使没有相转移剂，也表现出高效（在 3 M HNO 下 D > 10）和高选择性（在 3 M HNO 下 SF > 100）的萃取。
