摘要
本文应用连续流动注射分析仪(FIA),成功地实现了一次进样同时完成水质中挥发酚和氰化物、硫化物和总氮的测定[1,2]。分析结果准确、可靠,大大缩短了分析时间,加标回收率在95%--105%之间,相关系数均大于0.9995。并与传统的分光光度法进行了比较,在保证分析方法准确度的前提下,FIA法能提高检测灵敏度和检测速率,此方法简单、快速,适合于批量分析。
By means of using Flow Injection Analyzer and volatile phenol and cyanide or total nitrogen and sulfide in wa- ter can be determined at the same time successfully. The datum of determination is accurate, reliable and effective; short- en the determination greatly. The rate of recovery is between 95%--105%. And the coefficient of correlation can reach above 0.9995. Comparing with spectrophotography, the sensitivity and efficiency can be greatly improved by FIA under ensuring accuracy. The method is simple and fast, suitable for the batch determination in water.
