The selective transport of plutonium across supported liquid membrane using an indigenously synthesized 2-ethylhexyl 2-ethylhexyl phosphonic acid (KSM-17, equivalent to PC 88A) dissolved in dodecane as carrier has been investigated in this work. Laminar type polypropylene hydrophobic microporous membranes were used as solid supports. Transport experiments were carried out to evaluate the effect of varied hydrodynamic and chemical compositions of the system, i.e., stirring speed, carrier concentration, anionic composition (e.g. SO42-, NO3-, PO43-, ClO4-, Cl-) and acidity of source phase (SP) solution. Transport rates of plutonium from SP solutions of different anionic composition followed the order: ClO4- > NO3- > Cl- > SO42- > PO43-. Selective permeability of plutonium was observed in the presence of several cationic impurities such as Al, B, Be, Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Si, Zn, Ce, Dy, Fu, Gd and Sm. Using this technique, separation of plutonium from laboratory analytical waste was accomplished with an average flux 8.94 x 10(-6) mol m(-2) s(-1) and with an enrichment factor greater than 2. The product solution obtained from this process was in oxalate medium with negligible contamination from other cationic and anionic impurities. From this solution, plutonium was precipitated as Pu-oxalate for further processing. Reusability of the membrane support was found to be satisfactory.
