饮用水中氰离子含量一般很低,常用的分析方法有国家环境监测标准分析方法异烟酸吡唑酮和吡啶巴比妥酸比色法。两方法各有优点,但均需要试剂较多,操作麻烦,使分析工作多有不便。氰离子电极具有快速准确,操作简单的优点,对日常分析是一种值得推广的好方法。 Cyanide in drinking water content is generally low, commonly used analytical methods are the national environmental monitoring standard analytical methods isonicotinol pyrazolone and pyridine barbituric acid colorimetry. Both methods have their own advantages, but require more reagents, the operation is cumbersome, the analysis of more inconvenience. Cyanide ion electrode has the advantages of fast and accurate, simple operation, and is a good method to promote daily analysis.
