| 中文摘要 | the extraction behaviour of ce(iv), th(iv) and part of re(iii), viz., la, ce, nd and yb, has been investigated using di(2-ethylhexyl) 2-ethylhexyl phosphonate (dehehp,b) in heptane as an extractant. results show that extractability varies in the order: ce(iv) > th(iv) much greater than re(iii). therefore, it is possible to find the appropriate conditions under which ce(iv) can be effectively separated from th(iv) and re(iii). furthermore, stripping ce(iv) from the loaded organic phase can be carried out by dilute h2so4 with an aliquot of h2o2.roasted bastnasite made in baotou (china) by na2co3 and leached by hno3, there is about 50% ce mainly as tetravalent nitrate along with other re(iii) and th(iv) in the leachings. through fractional extraction, taking nitric acid leachings of roasted bastnasite as feed and dehehp as an extractant, we can obtain the ceo2 products with high purity of 99.9-99.99%, with a yield of >85%, in which tho2/ceo2 < 10(-4). |
