Se. Matthews et al., Extraction of lanthanides and actinides by a magnetically assisted chemical separation technique based on CMPO-calix[4]arenes, CHEM COMMUN, (5), 2001, pp. 417-418
A novel particulate system carrying CMPO ligands pre-organised on a calixar
ene scaffold has been synthesised and demonstrated to extract Eu3+, Am3+ an
d Ce3+ at high efficiency from simulated nuclear waste streams.
