This paper introduced the experimental set up method for studying the impacts of Cu 2+ on the sonofluorescence of three aqueous luminol alkaline solutions, and compared the sonofluorescence spectra of the solution with Cu 2+ with that of the solution without Cu 2+ . The spectra showed that the Cu 2+ increased the sonofluorescence intensity of the aqueous solutions of luminol NaOH and luminol Ca(OH) 2, and showed red shifts by 6nm and 9nm in their maximum sonofluorescence peaks, respectively. On the other hand, the Cu 2+ decreased the sonofluorecence intensity of the aqueous solution of luminol Na 2CO 3, and produced a blue shift by 5nm in its maximum sonofluorescene peak. But, it seems that the Cu 2+ didn′t change the sonofluorescence wavelength range of 370~750nm for above solutions. The experiment and results represented that, to say the least of it, the aqueous luminol alka line solution would become a luminescent system of sonofluorescence for detecting Cu 2+ or even other ions.
