Abstract
Separation and recovery of 152+154 Eu and 90 Sr 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+154 Eu and 90 Sr ions from nitrate medium at pH ~3.6. The separation factor was found to be ~4 for 152+154 Eu over 90 Sr. The aqueous feed of mass transfer coefficient (k i ) and the organic mass transfer coefficient (k m ) were calculated to be (1.52 and 4.5) × 10 ﹣ 2 cm/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+154 Eu and 90 Sr is five cycles.
