| 中文摘要 | phase behavior of the extraction system, cyanex 923-heptane/ce4+-h2so4 has been studied and compared with cyanex 923-heptane/h2so4 system. cerium(iv) is mainly extracted into the third phase, and its concentration in the third phase first increases with the increasing aqueous acid concentration, reaches maximum and then decreases. at higher acidity, cerium(iv) is hardly extracted in the third phase. the phase behavior and change of the contents of acid and water are similar to those in the acid system. the acid concentration increases with increase of the aqueous acid in the whole extraction region while the water content first decreases with it and then increases after the third phase formation. the third phase has a characteristic lamellar structure formed by the aggregates of cyanex 923 (.) (h2so4)(2) (.) h2o as those in the case of acid system. the third phase loaded ce(iv) has been used to prepare ultrafine ceo2 powder conveniently by precipitation with oxalic acid, and powders with size mostly smaller than 100 nm can be obtained. |
