磷酸盐共存体系中铵根的快速测定

Quick Determination of Ammonium in Phosphate Coexisten System

文章通过调节溶液的pH值,消除磷酸盐对甲醛法测定铵根的影响,针对溶液中磷酸盐存在的不同形态,建立了含磷酸盐体系中铵根的快速测定方法。该方法简便、快速,方法准确度较高,适合于生产中控分析。

By means of adjusting the pH value of solution,we eliminated the effect of phosphate on ammonium which is determined by formaldehyde method. Because there are different forms of phosphate in solntion, we put forward a new quick way to determine ammonium in phosphate coexistent system. The method is convnient and quick in operation, high in determining accuracy and suitable to central-controlled analysis.
