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

2

CO

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.
