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.
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。
Heated in water bath, uranyl ion and nitrate radical adsorbed on resin are replaced into solution by sodium bisulfate, then are determined by titanous method and spectrophotometry, respectively.
在水浴加热条件下，用硫酸氢根将吸附在树脂上的铀酰离子和硝酸根离子置换到液相中，之后分别采用亚钛法、分光光度法进行测定。
Thus the relations between densities of the solution and concentrations of uranyl nitrate and nitric acid are provided for.
提出了溶液比重和硝酸铀酰与硝酸浓度的关系式。
