Synergistic effect of various neutral donors in D2EHPA for selective neodymium separation from lanthanide series via HFSLM

다국어 초록 (Multilingual Abstract)

The separation of Nd(III) from lanthanide series via hollow fiber supported liquid membrane (HFSLM)using synergistic extractant was investigated. Optimum extraction and stripping obtained were 94.5%and 85.1% using D2EHPA and TOPO mixtures (0.5:0.5 M/M) as the synergistic extractant. Reaction orderfor both extraction and stripping were first-order with rate constants of 1.444 and 1.338 min1,respectively. The experimental results were used to correlate with the models. Results showed that theconcentration of Nd(III) from the experiment fitted in well with the model results. The average deviationwas 1.95% and 2.18% for predictions in both feed and stripping sides, respectively.
