HFSLM technique

Rathore et al. [65] studied the separation of plutonium from low plutonium content acidic waste using HFSLM technique impregnated with TBP. They fabricated the hollow-fiber test module using 20 Im of 33.91 cm surface area and 9 cm length. The waste solution was containing... 

A recent report with improved solvent containing 0.01 M DTBCH18C6 in 20% 1-octanol + 80% toluene has yielded rapid Sr(II) transport initially that was subsequently overwhelmed by large acid cotransport resulting in Sr(ll) back transport [75]. Recently, near quantitative transport of Sr(ll) from 3 M HNOj solution has been reported using the crown ether in 2-nitrophenyl-octyl ether (2-NPOE) and n-dodecane mixture [80]. The flux, however, was low that necessitated the use of HFSLM technique to increase the throughput for possible application on large scale. 

The HFSLM technique was successfully applied for the selective recovery of trivalent actinides over lanthanides using Cyanex-301 as the carrier. Similarly, the technique could be successfully applied for the separation of from °Sr using PC88A as the carrier. The HFSLM technique was also applied on process scale for the recovery of radiocesium, which revealed selective recovery of Cs(I) over other radiotracers ( Am, Eu, Sr, Fe, and Cr) with DFs of 100 for all the metal ions. High DFs as well as throngh-pnts suggested possible application of the system for the recovery of radio-cesinm from HLW.
