| 摘 要： | 研究了大孔弱碱性阴离子交换树脂D301从含大量钼、小量铼的H_2SO_4-(NH_4)_2SO_4溶液中分离铼和钼的性能。pH4—6范围内,D301对铼吸附率最大,而pH6时钼吸附率最高。二者在pH4时分离系数有最大值,β_(Re/Mo)=2277。最佳条件下纯铼的饱和吸附量为650mg/g树脂,工作吸附容量为244mg/g树脂。用8％NH_3·H_2O 10％NH_4NO_3和10％(NH_4)_2CO_3溶液分别洗脱铼和钼,二者可得到良好分离。

| Abstract: | The properties of adsorption and separation of Re and Mo from H2SO4-(NH4)2SO4solutions have been investigated. The static experiments indicate that the maximum adsorbtion rate (E) of Re takes place within pH 3 ?6 and 'that of Mo is observed at about pH 6 . The separation coefficient (p ) of both reaches maximum BR0/Mo =2277 at pH 4.0. The presence of SO42- in aqueous solutions decreases the E of Re. The dynamic experiments show that the D301 has great capacities for both Re and Mo. Re and Mo can be eluated selectively by 8 %NH3 ?H2O 10%NH4NO3 and 10% (NH4)2CO3 respectively. Therefore Re and Mo can be separated completely. |
