三聚氰酸纯度化学分析方法

Chemical Analysis Methods on the Purity of Cyanuric Acid

在水及非水介质中 ,用指示剂及电极电位判断终点 ,以酸碱滴定方法测定三聚氰酸纯度。结果表明 :用电位滴定和非水滴定较准确 ,相对误差分别为 0 .2 %和 0 .7%。

In the aqueous and non-aqueous mediums, the end point was judged with the indicator and electropotential . The purity of cyanuric acid was measured with acid-base titration methods. The results showed that the potentiometric and non-aqueous titrations are more correct , with the relative errors of 0.2% and 0.7% respectively.
