| 摘 要： | 由于铀溶液中的硝酸根对阴离子交换树脂具有较强的亲合力，相当低的硝酸根就足以干扰硫酸铀酰离子的吸附。利用一种高效吸附硝酸根的阴离子交换树脂吸附铀溶液中的硝酸根，再用NaOH溶液解吸，淋洗合格液中ρ(NO3^-)达60g／L左右。试验结果表明，用N-3树脂对铀溶液中的硝酸根进行吸附，可以实现从铀溶液中回收硝酸根的技术要求。

| Abstract: | Nitrate of low concentration can interfere with adsorption of uranyl sulfate anion on anion-exchange resins because the anion-exchange resins have a stronger affinity for nitrate in uranium solution. Nitrate can be adsorbed with a high efficiency resin, then desorbed by sodium hydroxide. The nitrate concentration is about 60 g/L in eluate. The research results show that nitrate can be recovered from uranium solution with N-3 anion-exchange resin. |
