摘要
本文发现钼(Ⅱ)与鲁米诺可以发生化学发光反应,产生很强的发光信号,不稳定的钼(Ⅱ)可在流动注射体系中通过锌汞齐还原柱由钼(Ⅵ)产生。此反应能够用于痕量钼的测定。方法的线性范围是1×10^(-9)~4×10^(-7)g/ml钼,相对标准偏差小于2%(n=11)。此方法用于测定几种水样和钢样中的痕量钼,得到满意的结果。
The chemiluminescence reaction of the Mo(Ⅱ)-luminol system was examined by the flow injection system with the Jones reductor. A new method for the determination of Mo on the basis of this reaction was reported. The calibration curve was linear over the concentration range of 1×10 -9-4×10-7g/ml for Mo and the relative standard deviation of determination was less than 2% (n = 11). The method has been applied to the determination of Mo in water and steel samples.
