The present extractant only exts. rare earths under the condition with high concn. of ammonium nitrate. Com. and the monomeric extractants show light rare earths selectivity. The calic[4]arene deriv. also show light rare earths selectivity, although the size effect (structural effect based on modification at upper rim) was not obviously obsd. due to poor soly. to org. solvent and insufficient extractability.英語フィールド
