“…Out of these, membrane based methods are becoming increasingly popular [8][9][10][11], not only due to low ligand inventory, but also because of easy scaling up option employing hollow fiber supported liquid membranes [12][13][14][15] and alleviation of problems such as third phase formation and phase entrainment. We have been investigating the transport behaviour of trivalent actinide ions using supported liquid membranes containing TODGA [16,17]. However, the transport behaviour of tetra-and hexavalent actinides is not well understood.…”
