Description

Transport of 99mTcO4 ions across TOPO-kerosene based supported liquid membrane was investigated at different concentrations of phosphoric acid as a feed solution and different concentrations of TOPO in the membrane, where 0.9% NaCl aqueous solution was used as a stripping solution. The flux of TcO-4 ions across this liquid membrane varied with the concentration of both H3PO4 and TOPO. The best permeability coefficient was obtained at concentrations, [H3 PO4] = 3 mole x l-1 and [TOPO] = 0.5 mole x l-1(P 2.08 x 10-9 m2 s-1). The results were utilized for the separation of 99mTc from 99Mo, where a selective and effective separation was obtained since no 99Mo transport across this liquid membrane was noticed while a high rate of 99mTc transport took place.
