| 英文摘要 | The solvent extraction of rare earths from chloride solution has been investigated using mixtures of 2-ethylhexylphosphonic acid mono-(2-ethylhexyl) ester (hehehp, p507) and organophosphorus acids [di-(2-ethylhexyl)phosphoric acid (hdehp, p204), isopropylphosphonic acid 1-hexyl-4-ethylocryl ester (hheoipp), bis(2,4,4-trimethylpentyl)phosphinic acid (cyanex 272), bis(2,4,4-trimethylpentyl)monothiophosphinic acid (cyanex 302), and bis(2,4,4-trimethypentyl)dithiophosphinic acid (cyanex 301)]. results show that the extractability of the selected extractants for rare earths decreases in the order: hehehp/hdehp > hehehp/cyanex 301 > hehehp/hheoipp > hehehp/cyanex 302 > hehehp/cyanex 272. a possible explanation of the different extractabilities is given based on the structure of the extractants. furthermore, the possibilities of the separation of adjacent rare earths with these mixtures were investigated according to the extractabilities; the results show the possibility of separating the rare earths.
