流动注射测量氰化物的方法

Flow Injection Method for Measuring Cyanide

为解决化学法的弊端,采用流动注射法对氰化物不同浓度标准物质的准确度、曲线、精密度和回收率等方面和测试时遇到的问题与解决方式进行系统性研究。实验结果表明,采用流动注射法检测氰化物具有准确度较高、精密度较好、良好的线性关系等优点,但回收率部分合格并分析原因。同时研究流动注射法对氰化物测试中出现的问题及解决方案,以及未来的研究方向。

In order to solve the shortcomings of the chemical method,this paper uses the flow injection method to study cyanide.The research content includes systematic research on the accuracy,curve,precision and recovery rate of different concentrations of cyanide standard materials,as well as the problems and solutions encountered during testing.The experimental results show that the flow injection method for detecting cyanide has the advantages of higher accuracy,better precision,and good linear relationship.But the recovery rate was partially qualified and the reasons were analyzed.At the same time,this paper studies the problems and solutions in the flow injection method for cyanide testing,as well as future research directions.
