摘要：

The extraction of Am(III) and Eu(III) from aqueous HClO//4 by BMPPT and TOPO in benzene was studied. The ligand BMPPT gave no detectable extraction in the ranges studied, but when BMPPT and TOPO were combined, a synergistic extraction was observed with a selectivity for Am(III) over Eu(III) (K//d//A//m equals 7. 5, Am/Eu equals 68, pH 3. 0, 0. 01 M left bracket TOPO right bracket , 0. 30 M left bracket BMPPT right bracket ).
