Sulfate anion content in tobacco tampers with combustibility, taste and quality.

摘要烟草中硫酸根离子的含量会影响其燃烧性、质量和吃味。

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。
