Development of liquid-liquid separation processes for the effective removal of the minor actinide Am(III) from used nuclear fuel using ligand-based strategies continues to be an area of significant research focus. The current investigation demonstrates the efficacy of a nitrogen-based bis-triazinyl pyridine (BTP) derivative to selectively extract Am(III) from nitric acid solutions containing light lanthanides. The performance of 3,3’-dimethoxy-phenyl-bis-1,2,4-triazinyl-2,6- pyridine (MOB-BTP) was compared to that of a camphor substituted BTP (CA-BTP). The results of this investigation demonstrate the novel 3,3’-methoxy-BTP extractant dissolved in a polar diluent was a more efficient extractant for Am(III) at a lower concentration than CA-BTP under comparable conditions.
