| 1 | Investigation on the Use of the Weakly Basic Polyacrylate Anion-Exchanger Amberlite IRA-68 for Sorption and Separation of Iminodiacetate Complexes of Rare Earth Elements显示文摘Based on the determined affinity series of rare earth element complexes with IMDA for the anion-exchangers, purification of macroquantities of Nd 3+ from Y 3+, Sm 3+ from Ho 3+, La 3+ from Nd 3+ and La 3+ from Pr 3+ on the weakly basic gel anion-exchanger Amberlite IRA-68 was studied. Using the presented method on 1 L of Amberlite IRA-68 in the acetate form, it is possible to obtain about 240 g Nd 2O 3 purified from Y 2O 3. Great difference in affinity of La 3+ and Nd 3+ as well as Pr 3+ complexes for this anion-exchanger in the acetate form indicates the possibility of applying this process for purification of lanthanum on the increased scale. On 1 L of Amberilte IRA-68 in the acetate form it is possible to obtain about 1125 g La 2O 3 purified from Nd 2O 3. On the basis of these results it can be assumed that unique properties of polyacrylate anion-exchangers enable their application for separation of rare earth elements. | Halina Hubicka , Dorota Kolodynska (Department of Inorganic Chemistry, Faculty of Chemistry, Maria Curie-Sklodowska University, Maria Curie-Sklodowska Sq.3, 20-031 Lublin, Poland) | 2002 | Journal of Rare Earths2002，20，6： | 2 |

| 3 | Investigation of Polyacrylate Anion-Exchangers for Separation of Rare Earth Element Complexes with EDTA显示文摘The rare earth complexes with EDTA, Ln(edta), show an unusual sequence of affinity for the anion exchangers. The sorption and chromatographic separation of Y 3+ for Nd 3+ complexes with EDTA was studied by using the strongly basic gel and macroporous polyacrylate anion exchangers, Amberlite IRA 458 and Amberlite 958, and the weakly basic gel polyacrylate anion exchanger, Amberlite IRA 68. The investigations on sorption and separation of rare earth complexes with EDTA on the polyacrylate anion exchangers applied mainly in the environment protection so far indicate that they can be applied in anionexchange separation of lanthanide complexes with aminopolycarboxylic acids. It was shown that the weakly basic polyacrylate gel anion exchanger Amberlite IRA 68 is the most effective in purification of Y 3+ from Nd 3+ in comparison with the strongly basic anion exchangers of this type. | Halina Hubicka(Department of Inorganic Chemistry, Faculty of Chemistry, Maria Curie Sklodowska University, 20 031 Lublin, Poland) | 2002 | Journal of Rare Earths2002，20，1： | 1 |

| 5 | Study on Separation of Lanthanum from Praseodymium Complexes with IMDA by Gel and Macroporous Anion Exchangers显示文摘During our studies on separation of rare earth complexes with aminopolycarboxylic acids on anion-exchangers, it is found that the affinity series of these elements with IMDA (Ln 3+ ∶IMDA=1∶2) for the anion-exchanger Dowex 1 in the acetate and IMDA forms is non-typical: Dy 3+ > Ho 3+ > Gd 3+ >Eu 3+ >Er 3+ >Y 3+ >Sm 3+ >Tm 3+ >Nd 3+ >Pr 3+ >>La 3+ . In the affinity series La 3+ is characterised as the lowest affinity in comparison with other rare earth elements, which indicates possibility of purification of La 3+ from all remaining lanthanides as well as Pr 3+ in the macro-micro systems by the frontal analysis technique. In the investigations strongly basic gel anion-exchangers Dowex 1×8 (type 1) and Dowex 2×8 (type 2) and strongly basic and weakly basic macroporous anion-exchangers Dowex MSA-1 and Dowex MWA 1 were used. Macroporous ion-exchangers have a sponge-like matrix which contains pores larger than molecules in size and the exchange of large ions is faster. The studies indicate that both the gel and macroporous anion-exchangers are useful for purification of La 3+ from Pr 3+ complexes with iminodiacetic acid. | Halina Hubicka, Dorota Drobek (Department of Inorganic Chemistry, Faculty of Chemistry,Maria Curie-Sklodowska University, Maria Curie-Sklodowska Sq. 3, 20-031 Lublin, Poland ) | 2000 | Journal of Rare Earths2000，18，2： | 0 |
| 6 | Effects of Polar Organic Solvent on Separation of Y(edta)^-/Nd(edta)^- Complexes on Polyacrylic Anion Exchangers显示文摘The use of polar organic solvents for the separations of rare earth elements (Ⅲ) is effective especially for their extensive separations despite the solubility limitations. The study shows that polyacrylate anion exchangers, particularly the weakly basic, gel anion exchanger Amberlite IRA 68, can be applied to the separation of rare earth complexes with EDTA in H2O-methanol and H2O-ethanol systems. In most cases the determined distribution coefficients of Ln3+ complexes with EDTA in mixed media like water-methanol on polyacrylate anion exchangers are larger than those in pure water (media.) | Halina Hubicka Dorota Kolodynska | 2005 | Journal of Rare Earths2005，23，1： | 0 |
