The complexation of An(III) and Ln(III) with PrOH- and EtOH-BPTD is studied by time-resolved laser fluorescence spectroscopy. [ML2]3+ is found for both Cm(III) and Eu(III), while [ML]3+ is only formed with Cm(III). Stability constants show a preferential coordination of Cm(III) over Eu(III) with PrOH-BPTD being the stronger ligand. The distribution of Am(III), Cm(III), and Ln(III) between an organic phase containing the extracting agent N,N,N′,N′-tetra-n-octyl-3-oxapentanediamide (TODGA) and aqueous phases containing PrOH-BPTD is studied as a function of time and temperature as well as the TODGA, BPTD, and HNO3 concentrations. A system composed of 0.2 mol/L TODGA and 0.04 mol/L PrOH-BPTD in 0.33–0.39 mol/L HNO3 allows for selective Am(III) back-extraction into the aqueous phase while keeping Cm(III) and Ln(III) in the organic phase, marking PrOH-BPTD as an excellent complexant for an optimized AmSel process (Am(III) selective extraction).}, cin = {IEK-6}, ddc = {540}, cid = {I:(DE-Juel1)IEK-6-20101013}, pnm = {1412 - Predisposal (POF4-141) / PATRICIA - Partitioning And Transmuter Research Initiative in a Collaborative Innovation Action (945077) / BMBF-02NUK059D - Spektroskopische Charakterisierung von f-Element-Komplexen mit soft donor-Liganden (f-Char) (BMBF-02NUK059D)}, pid = {G:(DE-HGF)POF4-1412 / G:(EU-Grant)945077 / G:(DE-Juel1)BMBF-02NUK059D}, typ = {PUB:(DE-HGF)16}, pubmed = {36274232}, UT = {WOS:000877103700001}, doi = {10.1021/acs.inorgchem.2c02871}, url = {https://juser.fz-juelich.de/record/910340}, }
