流动注射双环己酮草酰二腙光度法测定水中的铜

Determination of Copper in Water by Flow Injection BCO Spectrophotometry

为了克服传统分析法操作繁琐、分析时间长的缺陷,将流动注射分析技术和双环己酮草酰二腙光度法相结合,建立了测定工业废水中铜的快速、简便分析方法。方法的线性范围为0 mg/L～10 mg/L,分析速率可达55次/h,应用于工业废水样的测定,加标回收率在95.5%～104.0%之间,结果令人满意。

To overcome the defect of tedious manual procedures and time-consuming,a rapid method for determination of copper in water by flow injection BCO spectrophotometry is established.Calibration graphs are linear for ranges of 0 to 10 mg/L at a sampling frequency of 55/h.The proposed method is applied to the analyses of several wastewater samples,with recoveries of 95.5% to 104.0% by the standard addition method.
