| 中文摘要 | this paper presents the results of the adsorption of heavy rare earth ions (gd(iii), tb(iii), dy(iii), ho(iii), er(iii), tm(iii), yb(iii), lu(iii) and y(iii)) from hydrochloric acid solutions at 30 degreesc by the extraction resin containing 1-hexyl-4-ethyloctyl isopropylphosphonic acid (heoppa), which has higher steric hindrance, higher selectivities and lower extraction and stripping acidity than di(2-ethylhexyl)phosphoric acid (derpa) or 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester (heh/ehp). the dependence of acid concentration, flow rate and amounts of rare earth ions sorbed on the separation of er-tm, tm-yb and er-tm-yb mixtures has been studied. the baseline chromatographic separation of er-tm-yb mixture has been observed. satisfactory results with purity and yield of tm2o3>99.71% and >71.25%, er2o3>99-81% and >94.17%, and yb2o3>99.74% and >89.83%, respectively, have been obtained. the parameters such,as resolution, separation factors and efficiencies have been determined as a function of acidity, loading of rare earth elements and flow rates. the stoichiometry of the extraction of rare earth ions has been suggested as well. |
