Abstract
Extraction of complex (∝1P2W17O61Fe)7- by liquid surfactant
membrane The extraction of a Dawson-type heteropolyanion (∝1P2W17O61Fe) 7- was carried out by liquid surfactant membrane using (SPAN80) as surfactantand (TIBA) as extractant, internal phase used (NH4)2CO3. The extraction efficiency is 90 %. Then in order to regenerate the membrane, the stripping efficiency was given according to the concentration of the internal phase, the stripping efficiency is 76 % was obtained for (NH4)2CO3 concentration 1 M.
