流动注射分析法测定成烟产物中的Cu^(2+)

Measurement of Cu^(2+) in Smoke Products by Flowing Injecting Analysis

采用流动注射分析(FIA)技术建立了成烟产物中Cu2+的FIA分析方法,结果表明该方法所得数据可靠,具有较好的选择性和重现性,且样品测定频率大于30个/h,工作曲线γ≥0.9995,回收率大于95%,采用FIA实现了烟幕剂成烟产物中Cu2+的快速定量测定。

In this paper, a analytical method to determine Cu^2＋ in smoke products is developed by using flowing injecting analytic （FIA） technology. The results show that the data fi＇om the method are reliable and have good selectivity and repeatability. The measuring frequency of the method is above 30/hour, the working curve＇s radius of it is over 0.999 5, and the recovering ratio is more than 95% FIA can be used to realize the quick quantitative measurement of Cu^2＋ in smoke products of smoke gents and aerosois,
