| Abstract: | Liquid surfactant membrance separation of vanadium (IV) from acidic aqueous solution with ion exchanger, di ( 2-ethylhexyl ) phosphoric acid (P204), was studied. The various factors that effect on the separation including ( 1 ) emulsifier concentration, (2) acidity of internal phase, (3) pH of external phase, (4) Ve/Vw ratio and (5) the initial concentration of vanadium (IV) etc. have been determined. The stability of liquid membrane is not bad within 30 minutes ane the phenomena of breaking emulsion do not take place. The separation efficiency is more than 98%. |
