摘要
研究了用流动注射荧光法测定水中的镍和锌。镍和锌都使新点绿NG(NewportGreenTM)的荧光加强,分别测定时均有良好的线性关系,线性范围为10μg/L～200μg/L,检测限分别为8.1μg/L和8.4μg/L;镍与NewportGreenTM反应缓慢,而锌与NewportGreenTM是瞬间反应,因此,记录某一时间点的荧光强度,利用荧光强度的加和性原理,研究了同时测定水体中的镍和锌方法。
<Abstrcat>This paper presents a method for determination of trace Ni(Ⅱ) and Zn(Ⅱ) in water by fluorescence of Newport GeenTM with then coupled with FIA. A linear calibration curve was obtained in the range of 10 μg/L～200 μg/L for Ni(Ⅱ) and Zn(Ⅱ), with detection limit of 8.1,8.4 μg/L, respectively. And this method can also be used to determine trace Ni(Ⅱ) and Zn(Ⅱ) simultaneously.
