Sonoluminescence (cavitation glow) spectra of argon-saturated aqueous solutions of sodium, magnesium, and calcium at different values of the hydroacoustic pressure have been investigated. The results indicate that the increase in the solution pressure leads to a fast increase in the spectral intensity of the excited metal lines. This effect can be explained by the temperature growth inside cavitation bubbles, and it allows sonoluminescence spectra to be used efficiently for determination of the content of metals in liquid media.
