一氰是染料用的重要中间体，检测其无机杂质的含量是评价产品质量的一个重要指标。本文采用离子色谱的方法对不同厂家的一氰产品中无机离子进行分析，取得了满意的结果，对生产一氰和应用一氰工艺有参考作用。
Cyanide is an important intermediate for dyes used to detect the content of inorganic impurities is to evaluate product quality is an important indicator. In this paper, ion-exchange method was used to analyze the inorganic ions in a cyanide product from different manufacturers, and satisfactory results were obtained. It has a reference effect on the production of cyanide and the application of a cyanide process.
