摘要: A liquid emulsion membrane (LEM) containing PC-88A (2-ethylhexylphosphonic acid-2-ethylhexyl monoester) as the carrier extractant and SPAN-80 surfactant was used to pre-concentrate Am3+ from dilute acid solutions. Out of various stripping agents evaluated internal phase, 0.1 M oxalic found be most effective. The effect factors such as: external phase pH, equilibration time, concentration, SPAN 80 volume ratio, etc. on mass transfer investigated. broken by addition solvents acetone actual obtained after breaking agreed well with that difference method.
