A lower-rim (L-I), an upper-rim (L-II), and a both-side (L-III) diglycolamide-functionalized calix[4]arene were evaluated for the extraction of actinide ions such as UO22+, Pu4+, and Am3+ and fission product element ions such as Eu3+, Cs+, and Sr2+ from dilute nitric acid feed solutions. Conditions for quantitative extraction and stripping were found out and the kinetics of it were investigated for the extraction of Am3+. Though the actinide ions were generally extracted efficiently, UO22+ was poorly extracted. Supported liquid membrane (SLM) studies were carried out using the diglycolamide-functionalized calix[4]arenes under varying feed acidities and carrier extractant concentrations and the results compared with that of TODGA under identical conditions. A 0.01 M EDTA solution (pH 3.0) was found to yield quantitative transport of Am(III) using the extractants L-I L-III. The transport efficiency of the carrier solvent system was Eu3+ > Pu4+ > Am3+ >> UO22+, Diffusion coefficient values were both calculated by the Wilke-Chang equation and determined by the lag-time method. The SLM showed a poor stability, which did not improve by strip dispersion efforts. (C) 2013 Elsevier B.V. All rights reserved.
