A chemiluminescence (CL) signal was observed when alkaline earth metal ion solution, Mg 2+ or Ca 2+ or Ba 2+ , was injected into a reaction mixture of fluorescein and potassium permanganate. A possible CL mechanism is proposed based upon the CL, fluorescence and UV‐visible spectra. Furthermore, the feasibility of the application of these reactions to the analysis of these alkaline earth metal ions was evaluated and the analytical parameters of the methods were determined.
