Studies on the extraction behavior of octyl(phenyl)-N-N-diisobutylcarbamoylmethylphosphine oxide in polymeric adsorbent resins

This paper provides a comparison of the extraction of U(VI) and Am(III) from 3 M HNO3 by Amberlite XAD-4 and XAD-7 resins loaded with octyl(phenyl)-NN-diisobutylcarbamoylmethylphosphine oxide (OPhiCMPO). The paper also compares the breakthrough behavior during the sorption of Nd(III) and U(VI) from 3 M HNO3 by extraction chromatography using these resins as support material with OPhiCMPO as the stationary phase. The data indicate that XAD-7 is a better support material for extraction chromatographic applications.
