Abstract
Separation and recovery of 152+154Eu and 90Sr from radioactive waste using tracer concentration from active material from waste tank in the ET-RR1 Egypt via hollow fiber supported liquid membrane (HFSLM) were achieved. The Polypropylene was used as supporter to carrier 0.5M Cyanex301/kerosene (bis(2,4,4-trimethylpentyl)dithiophosphinic acid and 0.1MEDTA as stripping of 152+154Eu and 90Sr ions from nitrate medium at pH ~3.6. The separation factor was found to be ~4 for 152+154Eu over 90Sr. The aqueous feed of mass transfer coefficient (ki) and the organic mass transfer coefficient (km) were calculated to be (1.52 and 4.5) × 10﹣2cm/s, respectively. In addition, the mass transfer modeling was performed and the validity of the developed model from experimental data was found to join in well with the theoretical values when the Cyanex301 concentration is higher than 1% (v/v). The number of cycles evaluated for complete separation of 152+154Eu and 90Sr is five cycles.

Many of the radionuclides that are in the original waste have a short half-life of the tank, no longer detectable. The beta particle emitted in the decay of Y-90 has a high energy (2.2 million-electron-volts [MeV]) and is usually associated with the parent radionuclide Sr-90. It is the second most abundant radionuclide in the tank waste material. Sr-90 is always a component in effluent waste products to highlight the state of separation of 152+154Eu and 90Sr by hollow fiber supported liquid membrane
