A new selective and sensitive spectrofluorimetric method for the determination of trace amounts of nickel in industrial waste water has been developed. This method is based on the quenching of fluorescence of phenanthroline due to the formation of complex Ni (II)-Phen. The exitation and emission wavelengths were found to be 272 and 366 nm, respectively. There was a linear relationship in the range of 10.0-120 ng.mL-1 for Ni. This method is simple and rapid, and has been applied to the determination of nickel in industrial waste water.
已开发出一种用于测定工业废水中痕量镍的新型选择性灵敏荧光分光光度法。该方法基于镍（II）-邻菲罗啉配合物的形成导致邻菲罗啉荧光猝灭。激发波长和发射波长分别为272 nm和366 nm。镍含量在10.0 - 120 ng·mL-1范围内呈线性关系。该方法简单、快速，已应用于工业废水中镍的测定。
